Current Carrying Capacity of cables with different voltages

Not very well seemingly Darkwood so I wouldn't worry to much....

On the other hand think everyone needs to....

PANIC!!!!

A little knowledge is dangerous, and you have demonstrated that little knowledge. Each electron moves one place at a time, and there are billions and billions of them all queued up like traffic on a 5-lane motorway start stop traffic jam (except there are millions of lanes above and below and well as to the left and right, and the cars are really floating. One can only move forwards when the car in front has moved, and it can only move when the car in front of it moved.
Unfortunately, humans thought electricity was due to positive things, and it turned out electrons are negative, so just to confuse you further, the cars move backwards, as if in reverse, but don't assume that's the reason they move quite slowly. The analogy falls down here! So next time you look at a torch battery, remember the electrons come out of the -ve terminal and flow round the circuit to the +ve terminal!

Thats DC ... AC has no net migration of electrons but the electricity arrives at close to the speed of light just to add more confusion

Or the positive 'holes' migrating from +ve to -ve!

Somehow I think the student has been scared away....

Cant say I blame him LOL

 

[iamgary25]

I'm sure you lot answered my questions on page one lol

interesting reading the rest lol but thought not to get involved haha

Thanks though
