NEUTRAL AND HOT WIRES. Current flows from the panel toward the load along the hot wires and returns along the neutral. Each hot wire's copper tip ultimately connects to its control switch at the ...

We'll talk about three big ideas: electric potential difference (voltage), electric current, and electric field. Yes, they are all related, and I will show you how with some water and an LED.

The changing electric current in one wire makes a changing magnetic field. This changing magnetic field then induces an electric current in another loop. Also, the more loops you have ...
