Two inductors each of inductance L are connected in parallel. One more inductor of value 5 mH is connected in series of this configuration then the effective inductance is 15 mH. The value of L is .......... mH.

A

10

B

`5.0`

C

2.5

D

20

Text Solution

Verified by Experts

The correct Answer is:
D
Equivalent self inductance of two coils connected is parallel is `1/2`.
Now , `L/2 +5 =15`
`therefore L/2 =10 therefore` L=20 mH.
