8. A series RLC circuit is connected to a source of alternating emf as shown in L the figure. The components have values R = 5.20, L = 36mH, and C =0.41 F. The amplitude of the emf of the source is 100V. Initially, the frequency of the R emf is tuned to resonance. (a) What is the resonant frequency? n (b) At resonance, what is the amplitude of the voltage across the inductor? (c) At resonance, what is the amplitude of the voltage between points 1 and C 2 in the figure? (d) The frequency is changed to 4.7 x 105 radians per second. Now what is 2 the amplitude of the voltage between points 1 and 2
