Two coils of self inductances $L_1$ and $L_2$ are kept close to each other so that the effective flux in one is completely linked with the other. What is the mutual inductance M between them? |
$L_1 L_2$ ${L_1 L_2}^{-1}$ $(L_1 L_2)^2$ $(L_1 L_2)^{1/2}$ |
$(L_1 L_2)^{1/2}$ |
The correct answer is Option (4) → $(L_1 L_2)^{1/2}$ |
