Answer / vinay gupta

electrical current is actually the flow of free electrons
through a conductor when a potential difference is applied
on it. The electric field developed across the conductor
makes the electon to flow in a definite direction.

Answer / tauseef tarique, engineer(e)

Charge in motion, constitutes electric current. (either
electron or protone in motion). Also the rate of flow of
charge is electric current.

I=q/t

Answer / abhi

current is a rate of flow of charge per unit time.first
voltage is produce by any voltage producing device and due
to this current is produces.
