-0 marks
A coil with a quality factor (Q) of 10 is put in series with capacitor of , and the combination is found to draw maximum current when a sinusoidal voltage of frequency 50 Hz is applied. A second capacitor is now in parallel with the circuit. What should be the capacitance of for combined circuit to act purely as a resistance for a sinusoidal excitation at a frequency of 100Hz? Calculate the RMS current drawn by the combined circuit at 100 Hz if the applied voltage is 100 V(RMS).
