Question

In which of the following circuit is the current maximum just after the switch S is closed

• A. (i)
• B. (ii)
• C. (iii)
• D. Both (ii) and (iii)

Answer 1

Answer: (B)

(ii)

Answer 2

At t = 0 current through L is zero so it acts as open circuit. The given figures can be redrawn as follow.

$i_{1} = 0$ $i_{2} = \frac{E}{R}$ $i_{3} = \frac{E}{2R}$

Hence i₂ > i₃ > i₁
