A coil has a 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.

• A. P is doubled, Q is halved
• B. P is halved, Q is doubled
• C. P remains constant, Q is doubled
• D. P decreases 4 times, Q is doubled
