What is an effect of increasing Q in a series resonant circuit?
Fewer components are needed for the same performance
Parasitic effects are minimized
Internal voltages increase✓Bonne réponse
Phase shift can become uncontrolled
Explication
Q is the ratio of reactance to resistance in a series circuit, so raising it means the resonant current develops a larger voltage across L and across C. Those internal voltages reach Q times the applied voltage and can exceed component ratings even when the source voltage is modest.
