An LC circuit consists of a 3.30-H inductor and an 840-pF capacitor that initially carries a 105-C charge. The switch is open for t<0 and is then thrown closed at t=0. Compute the following quantities at t=2.00 ms:
(a) the energy stored in the capacitor
(b) the energy stored in the inductor
(c) the total energy in the circuit

A 15.0−μF capacitor is charged by a 150.0-V power supply, then disconnected from the power and connected in series with a 0.280-mH inductor. Calculate: (a) the oscillation frequency of the circuit; (b) the energy stored in the capacitor at time t = 0 ms (the moment of connection with the inductor); (c) the energy stored in the inductor at t = 1.30 ms.
In the circuit shown above, the capacitor is initially charged withcharge Q and the switch is open. At time t = 0, the switch isclosed.(a) What current flows in the circuit immediately after the switchis closed?(b) How much energy is stored in the capacitor immediately afterthe switch is closed?(c) How much energy is stored in the inductor immediately after theswitch is closed?(d) How much energy is eventually turned into heat by the tworesistors, starting from the time that the switch is closed until along, long time later?(e) How much energy is eventually turned into heat by the resistorR1 alone, starting from the time that the switch is closed until along, long time later?
Energy within an L-C Circuit As a function of time, what is the energy UL(t) stored in the inductor? Express your answer in terms of L and I(t) onstants Consider an L-C circuit with capacitance C, inductance L, and no voltage source, as shown in the figure (Figure 1). As a function of time, the charge on the capacitor is Q(t) and the current through the inductor is I(t) Assume that the circuit has no resistance and that at one time the capacitor was charged.
