PhysicsEasysingle choice

The figure shows three circuits with identical batteries, inductors and resistances. Rank the circuits in decreasing order, according to the current through the battery just after the switch is closed.

Options:

Answer:

Solution:

Just after switching on inductor behaves as open circuit

$\Rightarrow i_{1} = \frac{E}{\infty} = 0$ , $i_{2} = \frac{E}{R}$ and $i_{3} = \frac{E}{3 R}$

$\Rightarrow i_{2} > i_{3} > i_{1}$
