The definition of electric current is the rate of flow of electric charge over any plane of a wire. This flow of charge is also referred to as the electric current flowing through a wire.
I = Electric current = q / t
A = SI unit of electric current is Ampere.
The electric current’s conventional direction is the course of motion of positive charge.
Consider that a charge (q) rotates in a loop having a frequency (f),
Then the equivalent current, i = q * f
