JEE PYQ: Alternating Current Question 35
Question 35 - 2019 (12 Apr Shift 2)
Consider the LR circuit shown in the figure. If the switch S is closed at $t = 0$ then the amount of charge that passes through the battery between $t = 0$ and $t = \frac{L}{R}$ is:
(a) $\frac{2.7EL}{R^2}$ (b) $\frac{EL}{2.7R^2}$ (c) $\frac{7.3EL}{R^2}$ (d) $\frac{EL}{7.3R^2}$
Show Answer
Answer: (b)
Solution
$q = \frac{\epsilon L}{R^2 e} = \frac{EL}{2.7R^2}$.
