a) What is an electric current? What makes an electric current flow in a wire?
b) Define the unit of electric current(or Define Ampere).

a) A flow of charges or electrons through a conductor is called an electric current. The potential difference between the two ends makes the electric current flow through the wire.

b) Ampere is the unit of electric current. It is defined as a current flowing when 1 Coulomb of charge pass through any cross-section of a conductor in 1 second. Ampere is denoted by A.
