Two coils of self-inductance L(1) and L(...

Two coils of self-inductance `L_(1)` and `L_(2)` are placed closed to each other so that total flux in one coil is completely linked with other. If `M` is mutual inductance between them, then

`L_(1)+L_(2)`

`L_(1)L_(2)`

`sqrt(L_(1)L_(2))`

`(L_(1)L_(2))/(L_(1)+L_(2))`
