Question

Find the amount of electric current (in ampere) if a charge of 0.8 C flows through a conductor in 4 seconds.

• A. 0.2

Answer 1

The correct option is A 0.2
If a charge Q flows across any cross-section of a conductor in time t, then the current I through the cross-section is given by
$I=\frac{Q}{t}$
Here Q = 0.8 C and t = 4 s
Therefore, $I=\frac{0.8}{4}=0.2ampere$
