A circuit consists of a 20 nF capacitor in series with a 20 µH inductor. If a charge of 30 nC is put on the capacitor, there is an oscillation. (a) What is the maximum current that moves through the circuit? (b) Find the maximum energy in the inductor and the in the capacitor? (c) What is the angular frequency of oscillation? What is the period? (d) Assume the trace resistance in the circuit is 0.102. Describe quantitatively and qualitatively the oscillation in the circuit.

You are given an LC oscillator, with an  L = 3.3 mH  and a  C = 0.09 mF.  Initially, the inductor has a current flowing through it of 24 mA and the charge on the capacitor is zero at this same time. Find the maximum charge that we can expect on the capacitor at some later time. Assume that there are no internal resistance losses for these oscillations.

In the circuit shown in the Figure with 3.0 mH for the inductance and 6.0 uF for the capacitance, S1 has been closed for a long enough time so that the current reads a steady 3.50 A. Suddenly, S2 is closed and S1 is opened at the same instant. What is the maximum charge that the capacitor will receive?  What is the current in the inductor at this time? At an instant when the charge on the capacitor is 0.1 mC, what is the current in the inductor? At an instant when the charge on the capacitor is 0.1 mC, what is the rate at which the current in the inductor is changing?

(L11) At t = 0 s, a 3.53E-3 H inductor carries a 5.03 A current flowing from a to b, as shown in the figure. The current then decreases at a constant rate until it becomes zero at t = 4.10 s. The voltage is measured to be Va at point a and V₁ at point b. What is the voltage difference Va-Vb between t = 0s and t = 4.10 s (in V; answer the sign and magnitude)? a فیقققق L elle I b
