The switch in figure 1 has been closed for a long time. At t=0, the switch is opened. How would you estimate: (i) the initial condition (ii) the current through the inductor, i(t) for t > 0 ?

Here are the solutions to the questions:

Q.1 (c) The switch in figure 1 has been closed for a long time. At t=0, the switch is opened. How would you estimate:

(i) the initial condition

(ii) the current through the inductor, i(t) for t > 0 ?

Note: Figure 1 from the original problem shows a 16V source in series with a 20 $\Omega$ resistor and a switch. This combination is connected to two parallel branches: one with a 40 $\Omega$ resistor, and the other with a 30 $\Omega$ resistor in series with an inductor L.

**Step 1: Determine the initial condition $i_L(0
