Find the current drawn from the battery just after the switch is closed. Figure

  • A
    $\frac{E}{2 R}$
  • B
    $\frac{2 E}{R}$
  • Correct answer
    C
    $\frac{E}{R}$
  • D
    $\frac{2 E}{3 R}$

Solution

Just after closing the switch, inductor behaves as a open circuit, hence no current will flow in the inductor branch just after closing the switch. Hence, circuit diagram is redrawn as Figure Current, $\mathrm{I}=\frac{\mathrm{E}}{\mathrm{R}}$

Hence, the correct answer is option: 'C'.
