An LC circuit has an inductance of 28.0 mH and a capacitance of
164.0 µF. The capacitor is initially fully charged by a 13.10 V

An ideal L-C circuit (zero resistance) includes an inductor with
inductance L and a capacitor with capacitance C,
maximum charge on the capacitor Q, and a oscillation
period T. If we change out the inductor for one with an
inductance 4L, and we reduce the maximum charge on the
capacitor to Q/2, what is the new period of the L-C
circuit?

In an LC circuit you have what happens to the time required for
the capacitor charge to oscillate through a complete cycle if you

A single LC-circuit was observed in some time with its maximum

The sum of the electrical and magnetic energies in an

exactly half electrical and half magnetic, the capacitor charge is
5.30 mC, and the current is 8.00 A. Find (a) the capacitance, (b)
the inductance, and (c) the angular frequency of oscillation.

Consider an ideal LC circuit consisting of an (initially
charged) capacitor C and a solenoid L. Compare an LC circuit to a
spring with force Fspring= -kx=Ma where x(t) is the displacement of
the spring at time t and the acceleration is a. Kirchhoff’s circuit
laws applied to the LC circuit states that Vl + Vc = 0.
Let i=i(t) be the current in the circuit and q=q(t) is the
magnitude of the instantaneous charge on either capacitor plate.

[Series circuit analogue: RLC circuit with nonzero resistance R
and nonzero voltage E(t) as forcing function is analogous to a
forced damped spring/mass system.] Consider the RLC circuit with
inductance L = 8 henrys, resistance R = 16 ohms, capacitance C =
0.025 farads, and voltage E(t) = 17 cos 2t volts.

A series RLC circuit has a capacitor with a capacitance of 48.0
uF (microfarads) , an inductor with an inductance of 1.10 H and a
resistor with a resistance of 50.0 ohms. The circuit has a rms
current of 5.90 A when the frequency is 60.0 Hz. What is
?rms, the phase angle, and the average power loss?

An LC circuit is connected in series with the capacitor
initially charged. The period of oscillation is T. If at t=0, there
is no current in the circuit, what is the next time at which the

clearly:
1) T/4
2) T/2
3) 3T/4
4) T
5) 2T
