Question

If a charge of $0.8C$ flows through a conductor in $4$ seconds, is the amount electric current that flows through it.

• A. $0.5A$
• B. $0.2A$
• C. $0.25A$
• D. $0.01A$

Answer 1

The correct option is B $0.2A$

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 $q=0.8C$ and $t=4$ seconds
Therefore, $I=\frac{0.8}{4}=0.2Ampere$
