1. How does electricity work?
1.1. electricity works when a battery or some other power source makes the electrons in the wires to move. The electrons flows into a component like a light bulb. The it flows back to the power source. There are two types of electricity DC (directional current) and AC (Alternating current) DC is when the electrons flow in one direction. it usually uses a dry cell or alkaline battery. AC is when electrons flow in two directions so the electrons flow through one wire and back the same one. AC usually works off wall sockets.
