The second-order circuit shown below has the source voltage $V_s = 120$ V, inductance $L = 3$ mH, capacitance $C = 22$ µF, and resistance $R = 10$ ?.
The initial conductor current $I_{L0} = 0$A and the initial voltage of the capacitance is $V_{c0} = 0$ V. The switch is closed at $t = 0$. The expression of the
current is:
Select one:
? a. $i(t) = 8.6e^{-2850.1t}sin(3252t)$
? b. $i(t) = 6.5e^{-2200.t}sin(4226t)$
? c. $i(t) = 12.3e^{-1250.t}sin(2593t)$
? d. $i(t) = 16.1e^{-3000.t}sin(2480t)$
? e. none of these
