Formula: Series circuit (inductance)

Total inductance

Unit
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

Unit
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.
