Question

A charge of $420C$ flows through a conducting wire in 5 minutes. Find current flowing through the conductor.

• A. 1 A
• B. 1.2 A
• C. 1.4 A
• D. 1.6 A

Answer 1

The correct option is C

1.4 A

Given: Charge $Q=420C$

Time $t=5$ minutes $=5\times 60=300s$

Let the current be $I$.

We know that $I=\frac{Q}{t}$

$\Rightarrow$ $I=\frac{420}{300}=1.4A$
