A L-R circuit is shown in figure and switch is closed at $t = 0$ . Select INCORRECT option(s).

Answer:

C, D

Solution:

Equivalent inductance: $L_{e q} = \frac{2 L \cdot L}{2 L + L} = \frac{2 L}{3}$

$V = L_{e q} \frac{d i}{d t}$ , so $i = \frac{3 V}{2 L} t$ and $\frac{d i}{d t} = \frac{3 V}{2 L}$

Options (C, D) are the incorrect statements
