A mutual inductor consists of two coils ...

A mutual inductor consists of two coils `X` and `Y` as shown in Fig. in which one-quarter of the magnetic flux produced by `X` links with `Y`, giving a mutual inductance `M`. What will be the mutual inductance when `Y` is used as the primary?

A

`M//4`

B

`M//2`

C

`M`

D

`2M`

Text Solution

Verified by Experts

The correct Answer is:
C
the mutual inductance `M` remains the same whether `X` or `Y` is used as the primary.
