A circuit contains two inductors of self-inductance `L_(1)` and `L_(2)` in series (Fig) If `M` is the mutual inductence, then the effective inductance of the circuit shows will be

A

`L_(1) + L_(2)`

B

`L_(1) + L_(2) - 2M`

C

`L_(1) + L_(2) + M`

D

`L_(1) + L_(2) + 2M`

Text Solution

Verified by Experts

The correct Answer is:
D
When inductances are connected like this in series, then
`L = L_(1) + L_(2) + 2M`
