So for constant a power output ( amps x volts) the loss is the square of the current. Hence to raise the power by a factor of 2 - raising the voltage by a factor of 2 keeps the loss constant - raising the current raising the raising current by a factor of two raises the losses by a factor of 4.

This is why power lines are at 100,000 volts....

UMMM....yep thanks Arct1k.

"This amperage thing is just another thing to confuse me."

That didn't help but I think there might have been some important words missing in your main paragraph or double ups? Not sure sorry mate....

Cheers anyway, but I still don't get it
