Answer 1

Current is a fundamental quantity but it depends upon charge and time even it is not a derived quantity.

Explanation :

We know, the flow of charges through a conductor constitutes the electric current.

Electric current across an area held perpendicular to the side or the direction of the flowing of charge and thus its is stated as the amount of charge of charge flowing across that area per unit time.

thus,

$I=\frac{Q}{t}$

SI unit of Current :

I = $\frac{1 coulomb}{1 second}$

=  1 A

If one coulomb of charge crosses an area in one second , then the current through that area is 1 Ampere ( 1 A).
