Question

The emf induced in an inductor having a resistance of 2$\Omega$ varies a shown in figure. The charge induced in the inductor in 4 $\mu$s is

• A. 5 μC
• B. 10μC
• C. 4μC
• D. 20μC

Answer 1

The correct option is B

10μC

Induced charge =$\frac{\left(area\right)}{\left(R\right)}$=10$\mu$C
