Hey, guys. There is an interesting question about EM waves. I know electricity is transferred on transmission line as electromagnetic wave. But electromagnetic wave is one type of transverse wave, then how is AC electricity like? I feel it hard to imagine it.
Besides, conductors could be used to eliminate EM wave, for which metal grid in the door of microwave oven is a good example. Then why is the AC current different?
What do you think about it?
