Question

As shown in the figure, a battery of emf $E$ is connected to an inductor $L$ and resistance $R$ in series. The switch is closed at $t=0$. The total charge that flows from the battery, between $t=0$ and $t=t_c$ ( $t_c$ is the time constant of the circuit) is :

Select the correct option:

A

$\frac{E L}{R^2}$

B

$\frac{E L}{e^2}$

C

$\frac{\mathrm{EL}}{\mathrm{R}^2}\left(1-\frac{1}{\mathrm{e}}\right)$

D

$\frac{E L}{e^2 R^2}$

✓ Correct! Well done.

✗ Incorrect. Try again or view the solution.
