The inductors of self inductance L(1) ...

The inductors of self inductance `L_(1)` and `L_(2)` are put in series .

A

`L_(S) gt L_(m)`

B

`L_(S) =L_(m)`

C

`L_(S) lt L_(m)`

D

none

Text Solution

Verified by Experts

The correct Answer is:
C
`f=(c)/(lamda)impliesf_(m)=(c)/(lamda_(m))&f_(S)=(c)/(lamda_(S))`
`becauselamda_(m) gt lamda_(S)impliesf_(m)ltf_(S)`
`f_(m)=(1)/(2pisqrt(L_(m)c))&f_(S)=(1)/(2pisqrt(L_(m)c))`
`impliesL_(S)ltL_(m)`
