what is the value of power factor and explain sharpness of resonance concept?
Power factor
the ratio of the actual electrical power dissipated by an AC circuit to the product of the r.m.s. values of current and voltage. The difference between the two is caused by reactance in the circuit and represents power that does no useful work.
Frequency response is a measure of the amplitude of an oscillation as a function of frequency. Sharpness of resonance is defined by the Q factor, which is related to how quickly the energy of the oscillating system decays.
