Q#1 Sinusoidal Steady State Analysis GATE EE 1996 MCQ +2 marks -0.66 marks

A coil (which can be modeled as a series RL circuit) has been designed for high-Q performance at a rated voltage and a specified frequency. If the frequency of operation is doubled, and the coil is operated at the same rated voltage, then the Q-factor and the active power P consumed by the coil will be affected as follows
