RLC Circuits and Resonance

Q1: If the resistance in parallel with a parallel resonant circuit is reduced, the bandwidth

A disappears

B becomes sharper

C increases

D decreases

ANS:D - decreases

In parallel RLC circuit q=r""L/c.

So when r decreases q decreases.and b.w= resonant frequency/q factor.
So if q decreases then bandwidth must increase. Make high r-value get power loss to have high q in the circuit.
