RLC Circuits and Resonance

Q1:

A 15  resistor, a 220 H coil, and a 60 pF capacitor are in series across an ac source. What is the bandwidth of the circuit?

A 138 MHz

B 10,866 Hz

C 1,907 Hz

D 138 kHz

ANS:B - 10,866 Hz

XL=2 * π * f * l.

XC=1/(2*π*f*c),
when XL=XC.

f=1/2* π *(LC)^1/2,
And;

Q=1/R * (L/C)^1/2.
BW=f/Q.
