RLC Circuits and Resonance - Technical MCQs

Q1:

What effect will a parallel tank have upon final filter current?

A very little

B The bandpass frequencies will change.

C The frequency cutoff will change.

D The impedance will block output.

ANS:A - very little

At parallel resonance, the addition of current through inductor and capacitor is zero. So acts as an open circuit that doesn't allow current ideally. Hence option A
