Question

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

• A. $0.5A$
• B. $0.2A$
• C. $0.8A$
• D. $0.25A$

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