Given: The switch, which has been open for a very long time, is closed at t = 0.
Required: Determine the initial capacitor voltage, $V_{co}$, the steady-state capacitor voltage, $V_{c\infty}$, the time constant, $\tau$, in effect for t > 0 and the value of the capacitor voltage at t = 230.4 ms.
Solution:
$V_{co} = \boxed{} V$, $V_{c\infty} = \boxed{} V$, $\tau = \boxed{} ms$, $v_c(230.4 \ ms) = \boxed{} V$

Given: The switch, which has been closed for a very long time, is opened at t = 0.
Required: Determine the initial inductor current, $i_{Lo}$, the steady-state inductor current, $i_{L\infty}$, the time constant, $\tau$, in effect for t > 0 and the value of the inductor current at t = 11.88 µs.
Solution:
$i_{Lo} = \boxed{} mA$
$i_{L\infty} = \boxed{} mA$
$\tau = \boxed{} \mu s$
$i_L(11.88 \mu s) = \boxed{} mA$
