Answer:
[tex]I = \frac{dq}{dt}[/tex]
Explanation:
An electric current is caused by the motion of electric charge. It is defined as the rate of flow of electric charges through any cross-section. If a net charge of Δq passes through any cross-section in Δt time, then electric current I has been established.Its unit is Ampere.
As it is time rate of change of charges, So
[tex]I = \frac{dq}{dt}[/tex]
