Hoping someone can help. I have been studying RLC series circuits. The first set of questions gave the value of resistor, inductor and capacitor, which were calculated as follows:
To calculate resonant frequency:
fr = 1 / 2π√LC
fr = 1200Hz
To calculate Q:
Q = 2πfL / R
Q = 80
To calculate Bandwidth:
BW = fr / Q
BW = 15Hz
The question set then goes on to show another series RLC. It gives the value of the resistor, the resonant frequency, and the value of Q.
I have tried re-arranging the equations but can only find the bandwidth and have no idea how to find the inductor and capacitor values.
I have searched Google for answers but not turned up any equation to find L and C values.
Any help much appreciatted.
