# Charge, Electricity, And Circuits

11 Questions | Total Attempts: 237  Settings  Basically, the act of moving or revolving around as in a circle or orbit is what defines a circuit. In electricity, a circuit is an enclosed path of an electric current and it’s usually designed for a particular function. The quiz below on charge, electricity, and circuits will broaden your understanding. Give it a try!
