We know that the maximum power is lost at the resonant frequency,where the impedance is minimal. On the other hand, when the impedance is minimized, the charge coefficient is maximized. In resonance frequency amplitude of vibration is maximum.how is possible? Is there a relationship between resonant frequency and charge coefficient?
