A capacitor of unknown capacitance, a coil of inductance `L`, and a resistor of re-

sistance `R` are connected to a source of a.c. voltage `E=e_(0) cos omegat` (Fig. 112). The current in the circuit is `I = (E_(0)//R) cos omegat`.
Determine the amplitude U0 of the voltage across the capacitor plates.
