Are you retarded? you are correcting something that is already correct
>>681305378
what are you even talking about? these concepts are as foreign as you
>>681305378
There's only groundless outlets in shitty houses that haven't had their electric updated in over half a century.
>>681305378
obviously bait, but here I go anyway.
I was an electrician back in the 80's.
All modern American outlets have a ground prong.
Most modern appliances don't use it.
The purpose of the grounding wire is you hook it to the conductive shell of an appliance. Then, if a hot wire comes loose inside and touches the metal shell, it will trip the breaker instead of making the shell "hot".
Since most appliances are made of plastic, the ground prong usually servers no purpose.
>cucked to 110 volts?
Euro's use 240v because it means they can use smaller wires.
They're stuck with the standard now, but the original idea was to make household electricity somewhat more hazardous to save money on wiring.
...and now you know.
>>681305378
they believe in reducing the risk of shock by using lower voltage and not using another way for someone to be shocked.
Earth protects devices more than people.
>>681305888
trips checked
>>681305797
Seriously, all the plugs in my house have three holes. Just like OP's mom. And I use every hole. Just like OP's mom
>>681305857
so when the hot wire hits the metal case, since it is grounded, it blows the fuse. without the ground, the case would be charged and you would get a nasty shock right?
>>681305857
Amps kill, not volts.
Higher voltage means fewer losses during transport
>>681306120
higher voltage increases potential for shock, but reduces the current therefore damage
lower voltage reduces protential for shock, but increased damage if shocked.
50mA can kill
>>681306120
Volts times Amps kills. Even I know that and I'm retarded
>>681306272
so it is safer for me to get shocked from the 220v plug in my house instead of the 120v?
>>681306363
slightly yes
>>681305535
>>681305768
Device can be grounded.
How do you earth the device?
>>681306297
I have bad news for you anon.
0.001A and 50000V are non lethal but 0.1A and 5000V will kill you for sure
>>681306487
Same way as you ground one
>>681306434
weird. I've been shocked by 120 a bunch of times - but when I'm dealing with 220v I'm always scared as shit of it.
>>681306487

>without the ground, the case would be charged and you would get a nasty shock right?
Yep
>>681306120
>Amps kill, not volts.
Voltage and resistance (ohms) are causes, amperage is an effect.
Volts CAUSE amps.
Volts / Ohms = Amps
The higher the voltage, the higher the amperage.
Don't believe me? Go climb a high voltage power line tower and lick that big old wire.
>>681306623
sounds like you need to quit your job, or get better at not getting shocked
>>681306601
>>681306642
You missed my point.
>To earth a device.
Is this grammatically correct?
>>681306684
The grounding wire is connected to the conductive shell of an appliance. Then, if a hot wire comes loose inside and touches the metal shell, it trips the ELCB instead of making the shell live.
>>681306561
>>681306694
Yep. Told you I was a retard
>>681306363
Depends on your breaker/fuse size. Just hope that it trips out or you can get off that shit. 277 will make your muscles seize up and you have a hard time getting away from it

Your body isn't going to draw enough current to blow the fuse.
The higher the voltage, the more current will flow through your body.
Completely linear.

Volts CAUSE amps.
For a given resistance, a higher voltage results in more current.

>>681305857
Nail on the head. Also, the thin prong is grounded. The separate grounding wire allows a common ground if the current flowing out the second prong is high enough to cause concerns of ground float.

It's kind of sketchy, but the idea is the ground has a huge number of atoms.
These atoms can either accept, or give up a huge number of electrons quickly.
I forget the rest, but i think it does more for lightning and static charges than house current.

It's completely irrelevant at that point. 110 or 220V, it doesn't matter. There is plenty enough potential current there either way.

UK electricalfag here.
At 110 Volts there's significantly less chance of electrocution than 220 Volts. The US electrical system works just fine, as does the European system. Ours can kill more people if they're stupid enough to touch the live terminals, theirs can cause more house fires if the wiring is dodgy (lower voltage, same power requires more current, therefore more chance of heating in low-quality wiring).
tl;dr, both systems work just fine.
>>681307548
The deal is that the earthing wire is connected from the socket to the ground through the ELCB. Earth Leakage Circuit Breaker. If the ELCB detects any current flowing to earth whatsoever, it kills all power. That's how earthing protection works.
>>681307742
>Ours can kill more people if they're stupid enough to touch the live terminals
some dude said 220v was safe than 120v because of amps or something

It sure does matter. People get shocked with non-lethal currents all the time.

Static electricity seeks out a large volume of more or less neutral atoms (or an opposite charge).

I'm an Ausfag. Different name for the same device. Here they are either ELCBs or RCDs.
>>681307808
Power = Voltage times Current. Electrical devices require power to work, not Volts and Amps.
Halve the voltage and the device needs to draw twice the current for the same power. US mains operates at higher current, Euro operates at higher voltage.
There's no question that 220V can electrocute you better than 110V, it just can. The safety ground (earth) connection is there on Euro devices because of this increased risk. Still, the shrouded sockets we have in the UK really are just about the safest in the world. US plugs don't always have a ground, there's no fuse in the plug and they can often be inserted "upside down" where a UK plug has a fused live terminal and is assymetrical so it only goes in one way up. That last point is what gives the UK plug its superb safety, if you only have a single pole mains switch in a US plugged device then it's possible to plug it in and have it almost totally live even with its mains switch turned off.
One aspect of UK design that bugs me is the mains switches almost always are down-on. US devices have switches that come on when you switch them up, UK ones aren't so well designed as if you fall against them it's possible to accidentally switch them on.
>>681306960
In the event of an electrical fault which brings dangerous high voltage to the case of an appliance, you want the circuit breaker to trip immediately to remove the hazard. If the case is grounded, a high current should flow in the appliance ground wire and trip the breaker. That's not quite as simple as it sounds - tying the ground wire to a ground electrode driven into the earth is not generally sufficient to trip the breaker
>>681306033
under appreciated posting
>>681307960
>They have 250k-1000k volt and don't kill
Tasers use a very low duty cycle square wave.
They're only "on" for a tiny fraction of a second.
They send plenty of voltage, and hence amps through your body.
More than enough to kill you, except that it only lasts of a few milliseconds, so the total energy transmitted isn't enough to burn your skin and flesh.
>>681307845
>why does electricity flow to ground
it doesnt... really. all electricity is by default searching for the neutral point of the transformer that generated it. the one up the top of the pole that converted HV to your wall voltage. it wants to get back to there... but we channel it via your light sockets first.
if there is a fault to earth / ground then it flows along the green wire until it hits the MEN link where it flows happily back to the transformer along the neutral supply cable. fault loop completed, equilibrium. nothing passes through the ground... that would just energise a couple of square metres of dirt and shock anyone walking nearby.
understanding this shit is why its really not cool for smartarse neck beards to fiddle with system wiring. you will kill your dog.
>>681305857
I honestly don't know. Why does a higher voltage use smaller wires?
I suppose I could google it...

>Still, the shrouded sockets we have in the UK really are just about the safest in the world.
Murrican electrician here. Completely agree.
>>681308542
Because a device connected to a higher voltage can draw less current for the same power.
Watts (power) = Volts times Amps, higher voltage means less current, less current means less heating, less heating means you can use narrower cable.

>>681306799
Yes it is. It sounds horrible, but earth and ground can be used interchangeably
>>681308542
A thinner cable has higher resistance.
Higher voltage means it takes less current to transfer the same amount of power. Less current means more resistance, which means thinner cable.
>>681308700
Also higher efficiency, as the lower current wastes less energy heating the wire.
>>681308750
maybe in your cuck cuntry
>>681306799
No because eurocucks don't understand the difference between verbs and nouns. To those faggots a noun can suddenly be a verb in any context.
>>681307672
>Kek is that why the U.S Burma and Liberia are the only countries in the world who do not use the metric system?
All countries (including the U.S.) use the metric system for some stuff.
Almost all countries also use older, traditional units.
Ask a britbong how much he weighs, and you'll have to google what the fuck a "stone" weighs.
China, India, Japan, Taiwan and most of Europe use non-metric systems alongside metric, just like the U.S.
>>681308953
>Also higher efficiency, as the lower current wastes less energy heating the wire.
Resistance is inversely proportional to a wire's cross section.
Bigger wires mean less energy lost to heat.
That's why we use bigger wires for the 110 systems in Murrica.
>>681306751

>Amps kill not volts
is like "bullets kill, not guns." What kills you is measurable in amperage, but it's not a separate thing. Amps don't leap out of a piece of electricity to kill you, while volts stay safely inside.

>>681308953
Efficiency isn't that important in home wiring, only in long-distance transmission.
I guess the ideal consumer supply would be 110 Volts AC with adequate cabling and the UK's fused and grounded assymetric plug sockets.
Personally, I can see 100+ Volt supplies becoming a thing of the past eventually. Virtually every electronic device in the home operates internally at a maximum of 15 VDC, it's only things like kettles and hoovers and electric cookers that draw real power. I can see a time when you get maybe 220VAC delivered to an internal PSU that distributes low-voltage DC to devices and does away with almost all 100+ VAC outlets except in the kitchen and workshops.
>>681309604
Try working on old tube amps. Once you've had a jolt from 500 Volts DC you know what an electric shock is.
>>681307349
50Hz is awful but the general image quality was always better in PAL than the NTSC. PAL did not need the switch to HD but america greatly profited from the increase in image quality.
Also I never even had a TV that did only 50Hz and I still used a CRT made in the fucking DDR some a decade ago. Must be an extreme poorfag thing like people thinking that all CRTs had to blur the videe into a round ball.

your oversized cable is as much about defeating volt drop as it is current carrying capacity. 110v is not a good starting point when you are looking at a 70metre run to a pool shed.
you also need twice as many supply transformers because 110 doesnt punch as hard and the volts drop away in a blink of an eye.

>Celsius and Kelvin (essentially the same system) are based on a scale that makes more than a bit of sense, as opposed to the arbitrary bullshit rollercoaster that is Fahrenheit.
Nope, that's just so wrong.
Kelvin makes sense because it's the only one that doesn't allow negative temperatures.
Negative temperatures just don't make any sense. You can't have less than zero heat.
On the other hand, we don't want to say "It's only 270 out, better wear your big coat" vs "It's 300, I'm sweating my balls off!".
We want a scale that relates to real world outdoor temperatures.
Where I live outdoor temps range from 0 to 100 Fahrenheit, which makes more sense than -18 through 38 Celsius.

Thinner cable has higher resistance?

Voltage goes up in order to make current go down. If resistance goes up then current would stay the same potentially?

>Do electrons naturally flow towards earth? why would they do that?
Yes anon. This is the ground is at a lower potential than in the house,etc. You can think of this as there are lots of electrons above the ground and lesser electrons inside the ground. And since like charges repel, the electrons will be repelled away into the ground as there's less opposing force there.
I'm trying to simplify it, so this isn't actually super accurate.

Fuck you say? Fahrenheit may as well not be a unit of thermal measurement, just a percentage of what it 'apparently' feels like outside, as defined by two completely arbitrary points.
If Kelvin makes sense, so should Celsius. They're both the same measurement, only the Kelvin scale starts at absolute zero, whereas Celsius starts at freezing point of water. A far more useful scale for everyday measurement. "Oh, it'll just pop that in the oven at 180 degrees Celsius for a few minutes, because it's a far better scale for general use as my cake doesn't give half a fuck how hot it might 'feel' to me."

>>681310604
No, the two-pin plugs are reversible. It doesn't make any difference electrically which way the AC is connected but there are safety implications if the device only hasa single pole switch. In that case it's possible to have the switch only on the neutral wire so the device can be connected to the live terminal even with the switch off.

Euro's use 230 because everyone else had 240 but britbongs had 220 so it had to be made standard from the middle.
Ok, let's compare the different systems:
>Celsius
Anders Celsius creates a system where regular water at sea level freezes at zero and boils at one hundred.
Easy to understand for normal, non-retarded people.
>Kelvin
Lord Kelvin takes the Celsius scale, and winds it back to where the starting point is absolute zero (-273.15 C)
Not overly practical for everyday use, but certainly in the sciences, and makes perfect sense so long as you know absolute zero.
>Fahrenheit
Daniel Gabriel Fahrenheit. I'm just gonna quote wiki, because this shit is so retarded.
The lower defining point, 0 degrees, was established as the temperature of a solution of brine made from equal parts of ice and salt. Further limits were established as the melting point of ice (32 degrees) and his best estimate of the average human body temperature (96 degrees, about 2.5 degrees less than modern measurements).

C = Master Race
K = OK

crossed polarity will only work with simple restive loads.
and you cant dismiss the safety aspect as irrelevant. cross polarity was actually killing dozens of people a week.
that is why they added the ground wire.... then found it still wasnt sufficient to stop cross polarity so they conceded and added a non symmetrical phase / neutral pin outlet.. which is now finally a decent standard.
except people feel robbed having to change all their sockets *again* so they arent... and people are still dying by the day on cross polarised 2 pin toasters.

im just going to add that you really shouldnt compare kelvin to the other scales in terms of everyday handyness. as you mentioned, its only for science and in this field undisputed as for example diffusion terms often depend linear on the temperature and you want that 0K to mean no diffusion. the normalization is not really important and celsius scale has no real advantage

Resistance is inversely proportional to the cross-sectional area of the wire. Small gauge wire - higher resistance
Large gauge wire - lower resistance
Current is also inversely proportional to resistance. Less resistance more current and vice versa.
Also ftr, no current can flow without resistance. And there must be a potential difference (voltage) across that resistant material (wire).

You don't know the first thing about AC. A transformer connected live-neutral to AC works exactly the same as a transformer connected neutral-live. Doesn't matter if it's resistive, inductive, capacitative, whatever. Single-phase AC is AC whichever way round you connect the load.
Vacuum cleaner motors don't reverse if you swap the plug pins over, that's not a simple resistive load. In fact, nothing is a simple resistive load, everything is a complex impedance to some degree. You're talking out of your anus anon. Or you're getting confused with DC.

Just wiki it for more details, including a circuit schematic: https://en.wikipedia.org/wiki/Current_source
>current is the derivative of supply voltage and resistance
This is actually something which is taught wrong in many parts of the world.
People just go about saying V = I R without understanding the significance of that. I'll try to briefly explain it.
The best way to view that equation is as:
R = V/I
This is actually not a identity, but a definition of what resistance is. So it's basically saying, given any material(of a fixed shape, volume,etc), we can define something called the resistance for that object which is measured as the voltage to current ratio across the object(of course, this again depends on how its applied - the same material can have different resistances based on where the plates that apply the voltage are kept, ie, we need to mention the resistance of an object "across" sth).
More technically, it's
R = dV/dI, where we look at differential currents and differential voltages, and this is just a definition. The resistance of an object need NOT be a constant.
Now in case the resistance happens to be a constant, we can rewrite this as V = I*R, and say stuff like if V increases, I should also, etc.

An electric heater has a very low resistance when first switched on. As the elements heat up the resistance drops.A motor draws much more current starting up than it does running.
Very few loads are purely resistive.

>>681313048
>sure... but loads have a mostly fixed resistance
True, that's one of the challenges of system design, and for the most part, we can assume loads don't change with the current drawn.
>they only thing that we can vary is the amount of voltage applied to it.
Again, true, for most appliances.
>the current drawn by the system is the result.
Nothing wrong here either.
See anon, these are all right, but I was arguing your initial reply saying that higher current means less resistance. That's not true. Once you fix the load, the resistance is fixed. If higher current is drawn by the load, it doesn't mean the resistance has magically changed.
For any load, we can control only the current/voltage supply to it, and like I mentioned in my earlier post, if the resistance of that load is a constant, then there's a linear relationship between the two, but the current doesn't change the resistance of the object.

Well, since the neutral pin is connected to ground, it should be theoretically 0 V, but it'll be slightly more, say like 0.1V.
The reason is that we don't use perfect conductors, i.e, material with zero resistance. Metals, like copper wiring, etc come close but aren't exactly zero resistance.

>>681313651
Why does that matter? I wouldn't connect a load between neutral and ground, I'd connect it between live (phase) and neutral.
The potential difference (or in your words, "how many volts are on the pin") would vary from -240V to 0V to +240V.
And if I connected the phase and neutral the other way round to the load then the potential difference would vary from +240V to 0V to -240V. And there's no difference.
Now fuck off and learn how electricity works you dullard.

'Lorelle Young, president of the U.S. Metric Association, said the loss of Climate Orbiter brings up the "untenable" position of the United States in relation to most other countries, which rely on the metric system for measurement. She was not surprised at the error that arose.
"In this day and age when the metric system is the measurement language of all sophisticated science, two measurements systems should not be used," Young said.'

Depends on the measuring device used. Since this is a AC voltage, the voltage of the phase pin changes with time. It's 0 on average, and this is what a DC voltmeter would show(of course, it might be slightly more since the measuring instrument also draws current)
