47. (a) Yes, the voltage amplitude across the inductor can be much larger than the amplitude of the generator emf. (b) The amplitude of the voltage across the inductor in an RLCseries circuit is given by VIXILLLd==ω. At resonance, the driving angular frequency equals the natural angular frequency: ωωdLC1/. For the given circuit 61.0 H1000.(1.0 H)(1.0 10 F)LLXLC−
