Two coils each of self-inductance L are connected in parallel. If they are separated by a large distance, then what will be the self-inductance of combination?

Options

  1. AL 4
  2. BL 2
  3. CL
  4. D2 L

Correct answer

B. L 2

Step-by-step solution

In parallel combination, the resultant inductance L_P , 1 L_P = 1 L₁ + 1 L₂ = 1 L + 1 L = 2 L L_P= L 2
