"How does electricity move through wires?"

"It’s a complicated process, but there are charges inside wires and these charges can be acted on by an electric field. They can move through the wire in something that’s called an electric current.

"Moving charge is an electric current and we use that to push power through wires.

"The electric grid is one of the most complicated things ever built by humans. It’s this vast interconnection of wires and various components like transformers and power substations. It’s a vast network that’s designed to move tremendous amounts of energy power all over the world.
