For the circuit shown in figure beside, The expression for resonant
frequency with respect to the circuit elements is?"
Transcribed Image Text:For the circuit shown in figure beside, The expression for resonant frequency with respect to the circuit elements is?"
Expert Solution
Step 1

in given circuit R and C are parallel and that combination is in series with L

At resonance frequency the imaginary part of impedance is zero

let resonance frequency as w0 rad/s

and w as operating frequency

Step 2

For given circuit, total impedance with respect to source is

                                                               Zin=jwL+(R1jwC)      =jwL+R/jwCR+1jwC       =jwL+R1+jwRC       =jwL+R1+jwRC×1-jwRC1-jwRCZin =jwL+R1+(wRC)2+-jwR2C1+(wRC)2
