- LC Resonance circuits
The LC circuit
Design a parallel LC resonant circuit with a resonant frequency between 50-200 kHz. use = 10 - 100 , R = 1k
I choose the following values for
and :So the resonance frequency is
And
Construct the LC circuit using a non-polar capacitor
Measure the Gain as a function of frequency. (25 pnts)
Compare the measured and theoretical values of the resonance frequency ( ) (10 pnts)
Let's the plot the data from table above:
And let's zoom the graph above at resonance frequency:
So the experimentally measured resonance frequency is
And the predicted value of resonance frequency is
Questions
1.Is there a value of
in which at resonance. What is the value?(5 pnts)
