When two inductors are connected in series, the equivalent inductance is given by:
\(L_{eq}=L_1+L_2\)
When two inductors are connected in parallel, the equivalent inductance is given by:
\(L_{eq}={L_1L_2\over L_1+L_2}\)
Calculation
3H and 1H are connected are series.
L = 3 + 1 = 4H
4H and 12H are connected in parallel.
\(L={4\times 12\over 4+12}=3H\)
5H, 3H and 15H are connected in series.
Leq = 23 H
