CUET Preparation Today
Two inductor coils of self inductance, $L_1$ and $L_2$, having same length and same area of cross-section are placed so close that effective flux in one coil is completely linked with the other. The mutual inductance between them, is equal to |
$L_1 L_2$ $L_1/ L_2$ $(L_1 L_2)^2$ $\sqrt{L_1 L_2}$ |
$\sqrt{L_1 L_2}$ |
The correct answer is Option (4) → $\sqrt{L_1 L_2}$ |
