Stored Energy in LCR Circuit


Four resistors (R1 = 60 Ohms, R2 = 220 Ohms, R3 = 330 Ohms, and R4 = 480 Ohms), an ideal inductor (L = 8 mH), and a capacitor (C = 250 microF) are connected to a battery (V = 9 V) through a switch as shown in the figure below.


The switch has been open for a long time before it is closed at t = 0. What is Ustored, the total stored energy in the circuit elements (not including the battery) a long time after the switch is closed?

Ustored = J
