Resonance in AC Circuits - Part 2
This video explains sharpness of resonane and quality factor of the LCR circuit.
- 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.
- What is resonance frequency?
- What is Acceptor Circuit?
- What is Q factor?
- What happens to the circuit with very high Q value?
- What is a parallel resonance circuit? Why is it called so?
- Which circuit is used as filter circuit or rejector circuit and why?
- Can we have resonance in RL or RC circuit?
- How can Q factor be improved?
