RLC Circuits and Resonance - Engineering

Q1:

A resonant circuit has a lower critical frequency of 7 kHz and an upper critical frequency of 13 kHz. The bandwidth of the circuit is

A 7 kHz

B 13 kHz

C 20 kHz

D 6 kHz

ANS:D - 6 kHz

Bandwidth is known as upper half of frequency to lower half of frequency is known as bandwidth.
BW = f2-f1.
16-7 = 7khz.
