what is the difference between the two wires in an AC circuit, if the current is constantly switching direction? E.g. why do they say to always put the switch on the “hot” side?
In: Engineering
Because the neutral side is connected to the earth and the ground wire, so if you touch that, nothing happens even if you are standing on the ground, but if you touch the hot, suddenly there is voltage between you and ground, and current flows
