Answer :

The unit of electric current is the Ampere. As we know that the flow of electrons or charge in an electric circuit is called electric current. It is also defined as the flow of electric charge across a surface at the rate of a coulomb per second. So, it is represented by Ampere as it is a unit for the rate of coulomb per second.

Definition of Electric current

The flow of charged particles in an electric circuit is called Electric current

The S.I unit of electric current

Since the electric current is the flow of charge in a circuit at the rate of coulomb per second, the unit is Ampere or amp.

here, the unit of charge is coulomb and the unit of time is second

so,

Ampere=coulomb/sec

Thus, from the definition of electric current, it is known that flow of charge is measured in Ampere or amp.
