Inductors in Series:
Inductors in series are combined like resistors in series. Equivalent inductance (Leq) of two inductors in series that was shown in the Figure is given through Equation (3-2).
Leq = L1 + L2 + ... Ln (3-2)
Inductors within parallel are combined like resistors in parallel as given by Equation (3-3).
1/ Leq = 1/ L1 + 1/ L2 +...1/LN (3-3)
