Question

Just before the switch is opened at $t=0$ in Eigure P4.21, assume the current through the inductor Page 318is $i_L=1.5 \mathrm{~mA}$. Determine the voltage $v_3$ across $R_3$ immediately after the switch is opened. Assume $V_S=12 \mathrm{~V}, R_1=6 \mathrm{k} \Omega, R_2=6 \mathrm{k} \Omega, R_3=3 \mathrm{k} \Omega$, and $L=0.9 \mathrm{mH}$.

The switch is opened at t = 0, after it was closed for a long time. If L = 0.9mH, Vs = 12V, R1 = 6kΩ, R2 = 6kΩ, and R3 = 3kΩ, determine iL(t) for t ≥ 0. Then, find vL(t).
