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).

L_eq  = L₁  + L₂  + ... L_n                                   (3-2)

Inductors within parallel are combined like resistors in parallel as given by Equation (3-3).

1/ L_eq   = 1/  L₁ + 1/ L₂ +...1/L_N             (3-3)
