Question

Hola mate.. Try this............. ☺☺☺, ​

Answer 1

Given,

Two coils of cell inductance = L1 and L2

So,

First cell inductance = L1

Second cell inductance = L2

One coil is completed linked with other inductance.

M is mutual inductance between them

Then.

M =√L1L2

So

The correct answer is option.D
