Formula: Series circuit (inductance)
Two coils connected in series

Total inductance

Total inductance of \(n\) coils connected in series. In this case, the individual inductances add up.

For two coils connected in series (\(n=2\)), the total inductance \(L\) is the sum of the two individual inductances: $$ L ~=~ L_1 + L_2 $$

Individual inductance

Inductances of individual coils connected in series. \(L_1\) is the inductance of the first coil, \(L_2\) is the inductance of the second coil and so on. \(L_n\) is the inductance of the last, \(n\)th coil.
