Question

Find the electric current that flows through a conductor if a charge of $4.2C$ flows through it in $2.1seconds$.

• A. 0.5 Ampere
• B. 2 Ampere
• C. 0.25 Ampere
• D. 0.01 Ampere

Answer 1

The correct option is B

2 Ampere

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 $q=4.2C$ and $t=2.1seconds$
Therefore, $I=\frac{4.2}{2.1}=2Ampere$
