Two inductors of inductance L each are connected in series with opposite magnetic fluxes. The resultant inductance is
(Ignore mutual inductance)

A

zero

B

L

C

2L

D

3L

Text Solution

Verified by Experts

The correct Answer is:
C
When magnetic fluxes are in opposite diretion
`L'=L_(1)+L_(2)-2M`
Ignoring M=0
The resultant inductance is `L'=L+L=2L`
