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

Options

  1. AE2R\frac{E}{2 R}
  2. B2ER\frac{2 E}{R}
  3. CER\frac{E}{R}
  4. D2E3R\frac{2 E}{3 R}

Correct answer

C. ER\frac{E}{R}

Step-by-step 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 Find the current drawn from the battery just after the switch is closed. Current, I=ER\mathrm{I}=\frac{\mathrm{E}}{\mathrm{R}}
