Question

Find the electric current that flows through a conductor if a charge of $0.8C$ flows through it in $4$ seconds.

• 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, $q=0.8Candt=4s$
Therefore, $I=\frac{0.8}{4}=0.2A$
