Solution:

$ \text { Draw ckt for } t\lt0 \quad[t=\overline{0}] \\ $

enter image description here

from fig.

$ \begin{aligned} \\ I_0 &=I(\overline{0})=2 \text { Amp } \quad \because I_0=\frac{20}{10} \\\\ \&_0 &=V_c(\overline{0})=0 \text { Volts } \\ \end{aligned} \\ $

Draw ckt. at

$t=0^{+}$

enter image description here

$ \text { Draw ckt for } t\gt0 \\ …
