Inductors In Series

Inductors are said to be connected in “Series” when they are daisy chained together in a straight line, end to end. In the Resistors in Series tutorial we saw that the different values of the resistances connected together in series just “add” together and this is also true of inductance. Inductors in series are simply “added together” because the number of coil turns is effectively increased, with the total circuit inductance LT being equal to the sum of all the individual inductances added together.

L T = L1 + L2 + L3 + ...
I = IL1 = IL2 = IL3 + ...
VS = VL1 + VL2 + VL3
