Step-by-step 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
![I = (dq)/(dt)](https://img.qammunity.org/2020/formulas/physics/middle-school/tbr13ehncnv493g7sr9i04dhpf80p0x5at.png)
