Define Q factor? write its physical significance.
Answers
In physics and engineering the quality factor or Q factor is a dimensionless parameter that describes how under-damped an oscillator or resonator is, or equivalently, characterizes a resonator's bandwidth relative to its center frequency.
Significance : Q factor determines the sharpness of the resonance curve, if Q is high, the resonance curve is sharper and the energy lost by the circuit is less. Sharpness: Sharpness of a AC circuit is related to the Q factor. IF the sharpness is more we get a clear effect in the system and resistance is less.
