Question

A coil (which can be modelled as a series RL circuit) has been designed for high Q performance. The voltage is rated at and a specified frequency. If the frequency of operation is increased 10 times and the coil is operated at the same rated voltage. The new value of Q factor and the active power P will be?

Options:

A . P is doubled and Q is halved

B . P is halved and Q is doubled

C . P remains constant and Q is doubled

D . P decreases 100 times and Q is increased 10 times

Answer: Option D
Answer: (d).P decreases 100 times and Q is increased 10 times
