Question:
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?
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?
Show Hint
Inductors in parallel combine like resistors: $1/Lₑq = 1/L₁ + 1/L₂$.

- $\fracL4$
- $\fracL2$
- L
- 2L
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: For inductors in parallel with no mutual inductance, $\frac1Lₑq = \frac1L + \frac1L = \frac2L$.
Step 2: $Lₑq = L/2$.
