8. A series RLC circuit is connected to a source of alternating emf as shown in the figure. The components have values $\mathrm{R}=5.2?,\mathrm{L}=36\mathrm{mH}$, and $\mathrm{C}=0.41?\mathrm{F}$. The amplitude of the emf of the source is $100\mathrm{V}$. Initially, the frequency of the emf is tuned to resonance. (a) What is the resonant frequency? (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 2 in the figure? (d) The frequency is changed to $4.7\times 10^5$ radians per second. Now what is the amplitude of the voltage between points 1 and 2 ?
