Question

Two coils of self inductance $L_1$ and $L_2$ are connected in series combination having mutual inductance of the coils as M . The equivalent self inductance of the combination will be

Select the correct option:

$\frac{1}{L_1}+\frac{1}{L_2}+\frac{1}{M}$

$\mathrm{L}_1+\mathrm{L}_2+\mathrm{M}$

$\mathrm{L}_1+\mathrm{L}_2+2 \mathrm{M}$

$\mathrm{L}_1+\mathrm{L}_2-2 \mathrm{M}$
