Resonance in AC Circuits - Part 1
- An inductor, a capacitor and a resistor are connected in series across an ac source of voltage. If the frequency of the source is decreased gradually. the reactance of: (a) both the inductor and the capacitor decreases. (b) inductor decreases and the capacitor increases. (c) both the inductor and the capacitor increases. (d) inductor increases and the capacitor decreases.
- A sinusoidal voltage of peak value 10 V is applied to a series LCR circuit in which resistance capacitance and inductance have value of 10ohm, 1µF and 1H respectively .find (i)the frequency which drives the circuit at resonance (ii)quality factor of the circuit.
