Question

An inductor of 0.5 mH, a capacitor of 200 μF and a resistor of 2 Ω are connected in series with a 220 V ac source. If the current is in phase with the emf, the frequency of ac source will be ______×10^2 Hz.

Correct answer: 5. Given here: L=0.5×10^(-3) H C=200×10^(-6) F R=2 Ω. If current is in phase with emf, so this is the condition of resonance. f=f_R=1/(2π√LC)=1/(2×3.14√LC) f=1/(6.28√(0.5×10^(-3)×200×10^(-6)))=503.55 Hz=5.03×10^2 Hz
