What is the significance of quality factor in an AC circuit?

Q factor is alternatively defined as the ratio of a resonator’s centre frequency to its bandwidth when subject to an oscillating driving force. These two definitions give numerically similar, but not identical, results. Higher Q indicates a lower rate of energy loss and the oscillations die out more slowly.

What is the physical significance of quality factor?

Answer: In physics and engineering the quality factor or Q factor is a dimensionless parameter that describes how underdamped an oscillator or resonator is. It is approximately defined as the ratio of the initial energy stored in the resonator to the energy lost in one radian of the cycle of oscillation.

What is Q factor give its significance?

The Q factor or quality factor gives the sharpness of resonance obtained in the LCR circuit. If Q value is more, then the resonance will be very sharp and if it is less then resonance will be weak giving rise to weaker circuit.

What is quality factor and its importance in measurement?

Q factor (also known as Quality Factor or Q-factor) is defined as a dimensionless parameter that describes the underdamped condition of an oscillator or resonator. The quality factor measures the performance of a coil, a capacitor, or an inductor in terms of its losses and resonator bandwidth.

What is the significance of quality factor in RL and RC circuit?

The quality factor relates the maximum or peak energy stored in the circuit (the reactance) to the energy dissipated (the resistance) during each cycle of oscillation meaning that it is a ratio of resonant frequency to bandwidth and the higher the circuit Q, the smaller the bandwidth, Q = ƒr /BW.

What is the quality factor of a circuit?

The quality factor Q for the circuit is the electric energy stored in the circuit divided by the energy dissipated in one period. The Q of a circuit is an important quantity in certain applications, as in the case of electromagnetic waveguides and radio-frequency cavities where…

What is meant by quality factor of the circuit?

What is quality factor in electrical engineering?

The quality factor Q for the circuit is the electric energy stored in the circuit divided by the energy dissipated in one period.

What is the quality factor in AC circuit how it is related with sharpness of resonance?

Q-factor
The sharpness of the resonance is associated with the Q-factor of the RLC circuit. The sharpness characterizes how fast the energy decays in an RLC circuit that is connected to an alternating voltage.

How sharpness of the resonance circuit is related to quality factor Q?

The $Q$-factor determines the sharpness of the resonance curve. If the resonance is less sharp, not only the maximum current is less, the circuit is closer to resonance for larger values of $\Delta \omega $and frequencies and tuning of the circuit will not be good.
