Question

Two inductors each equal to $L$ are joined in parallel. The equivalent inductance is

• A. $\text{zero}$
• B. $2L$
• C. $L$
• D. $\frac{L}{2}$

Answer 1

The correct option is D $\frac{L}{2}$

Inductances are added like resistors.
$\frac{1}{L_{eq}}=\frac{1}{L}+\frac{1}{L}$
$\therefore L_{eq}=\frac{L}{2}$
