(II) Capacitors made from piezoelectric materials are commonly used as sound transducers (“speakers”). They often require a large operating voltage. One method for providing the required voltage is to include the speaker as part of an LRC circuit as shown in Fig. 30-29, where the speaker is modeled electrically as the capacitance C = 1.0 nF. Take R = 35 Ω and L = 55 mH, ( a ) What is the resonant frequency f 0 for this circuit? ( b ) If the voltage source has peak amplitude V 0 = 2.0 V at frequency f = f 0 , find the peak voltage V C 0 across the speaker (i.e., the capacitor C ), ( c ) Determine the ratio V C 0 / V 0 .

Calculate the magnitude and direction of the durrents in each resistor of fig. 19-58.
There are two solutions to this problem given on the website. However, both are leaveing out steps.
The switch in Fig. 8.73 is moved from A to B at t = 0 after being at A for along time. This places the two capacitors in series, thus allowing equal andopposite de voltages to be trapped on the capacitors. (a) Determine vi(0),v2(0-), and vr(0-). (b) Find vi(0+), v2(0+), and vr(0+). (c) Determine thetime constant of vr(t). (
the capacitor discharged (V = 0, Q = 0) Should you close the switch? Why or why not?
