RLC Circuits and Resonance - Engineering

Q1:

A certain series resonant circuit has a bandwidth of 2 kHz. If the existing coil is replaced with one having a higher value of Q, the bandwidth will

A increase

B remain the same

C decrease

D be less selective

ANS:C - decrease

But Q = W*R/L, so if frequency is increased to increment in the Q, there will be no effect on BW.
