What is the significance of Q factor in AC circuit?

Q Factor definition In an AC system, the Q factor represents the ratio of energy stored in the capacitor to the energy dissipated as thermal losses in the equivalent series resistance. For example, a capacitor that is capable of storing 2000 joules of energy while wasting only 1 joule has a Q factor of 2000.

What is the significance of Q factor Class 12?

Hint: The quality factor or ‘Q’ is a dimensionless quantity that describes the nature of damping in a resonating circuit. It is indeed the ratio of maximum energy stored in the circuit to the energy dissipated during each cycle of oscillation.

What is the quality factor of the circuit?

Hint: The quality factor or ‘Q’ is a dimensionless quantity that describes the nature of damping in a resonating circuit. It is indeed the ratio of maximum energy stored in the circuit to the energy dissipated during each cycle of oscillation. of its peak value i.e. current is it’s 1√2times of its peak.

What does a high quality factor mean?

• Substrates with high quality factor Q. Q factor describes if an oscillator or resonator is underdamped, overdamped, or critically damped. Higher Q indicates that the oscillations die out more slowly (a lower rate of energy loss relative to the stored energy of the resonator).

Why should the quality factor have high value in receiving circuits?

The quality factor has high value in receiving circuits in order to get a sharp gain for the desired channel frequency.

What is the quality factor of the circuit at resonance?

Q
The Q, or quality, factor of a resonant circuit is a measure of the “goodness” or quality of a resonant circuit. A higher value for this figure of merit corresponds to a more narrow bandwidth, which is desirable in many applications.

What is quality factor express in terms of LCR?

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. Quality factor is expressed as, Q-factor is a dimensionless quantity.
