Best Answer

An electrical circuit is used to guide electricity through a path. This is used because when electricity is guided to various things it can power them.
Anything that uses electricity.

It's called a circuit because the electrons have to circulate back to where they came from.

A battery has two poles. The circuit is only complete when both terminals are connected via the device(s) driven.

A generator has two poles from the coil inside. Electricity can only flow when both ends of the coil are attached.
