How does AC electricity travel anywhere if it is going “back and forth”?
In: Engineering
Think of a device like a Newton’s Cradle (https://en.wikipedia.org/wiki/Newton%27s_cradle) and assuming all the balls are still. If you push on the end of one ball, all the balls move in the same direction, and if you push on the other end, they move in the other direction. That’s basically how AC current works: all the electrons are moving back and forth.
