\( \cdot \)\( \cdot \)48 Figure 31-32 shows a driven RLC circuit that contains two identical capacitors and two switches. The emf amplitude is set at 12.0 V , and the driving frequency is set at 60.0 Hz . With both switches open, the current leads the emf by \( 30.9^{\circ} \). With switch S 1 closed and switch S2 still open, the emf leads the current by \( 15.0^{\circ} \). With both switches closed, the current amplitude is 447 mA .What are (a) \( R \), (b) \( C \), and (c) \( L \) ?
