For a current to flow continuously through a circuit, the circuit must be:

An electrical current is an electrical charge flowing around a circuit. Carried by billions of tiny particles called electrons, the charge is already in the wires.

Explanation:

There are three basic conditions for the electric current flow is to be given below:-

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
