emi

Question: Two coils of self inductance ${L_1}$ and ${L_2}$ are placed closer to each other so that total flux in one coil is completely linked with other. If $M$ is mutual inductance between them, then

1) $M = {L_1}{L_2}$

2) $M = {L_1}/{L_2}$

3) $M = \sqrt {{L_1}{L_2}} $

4) $M = {({L_1}{L_2})^2}$

Solution:

Explanation: No Explanation
