What is Q factor in electrical circuits?

The quality factor or Q factor is a measure of the performance of a coil, capacitor inductor in terms of its losses and resonator bandwidth.

What is unit of quality factor?

Quality factor (Q) or coil Q-factor is a dimensionless unit for the losses of a coil, quartz, or a resonator. They are inversely proportional for the coil quality and are calculated from the ratio of reactance to ohmic resistance. The reciprocal value of quality is the loss factor (d).

What do you mean by quality factor?

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 a quality factor circuit?

The Q, or quality, factor of a resonant circuit is a measure of the “goodness” or quality of a resonant circuit. A practical application of “Q” is that voltage across L or C in a series resonant circuit is Q times total applied voltage.

What is quality factor in LC circuit?

Quality factor controls the damping of oscillations. If Q is less than 1/2 , it is underdamped and losses in the circuit are minimal and oscillations will be sustained longer. Q factor is ratio of reactance to resistance in LC circuits. Resistive losses in the inductance will affect the Q factor.

What is meant by quality factor?

What is the reciprocal of quality factor?

Dissipation Factor
Dissipation Factor is the reciprocal of quality factor.

What is quality factor and dissipation factor?

In physics, the dissipation factor (DF) is a measure of loss-rate of energy of a mode of oscillation (mechanical, electrical, or electromechanical) in a dissipative system. It is the reciprocal of quality factor, which represents the “quality” or durability of oscillation.
