Inductors & DC Transients (Mixed)

Three inductances are connected as shown in figure. The equivalent inductance is

Show answer and solution

Answer: (d)

Inductors combine like resistors (no mutual coupling).
Two $\frac{L}{2}$ in parallel: $\frac{(L/2)(L/2)}{L/2+L/2} = \frac{L}{4}$
Add the series $\frac{3}{4}L$ : $L_{eq} = \frac{L}{4} + \frac{3L}{4} = L$
So the answer is (d) $L$ .
