Chapter 30, Problem 66P
(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 f0 for this circuit? (b) If the voltage source has peak amplitude V0 = 2.0 V at frequency f = f0, find the peak voltage VC0 across the speaker (i.e., the capacitor C), (c) Determine the ratio VC0/V0.
