double pronged outlets, how come they are never plugged in wrong?

Question

So in England we have the ground prong so our cables are all the same, however I know in the states and other places they don’t, so how come no damage is caused if the positive and negative are the wrong way around?

Answer 1

Alternating current does not have positive and negative. It has a hot and a neutral. For AC power it generally doesn’t matter which way something is plugged in.
