Hi, i am studying parallel resonant circuits in school now and am having some trouble with some of the results from a lab I was assigned. ...........
The circuit was constructed using a 4.7K
hm: resistor in series with the LC circuit. The source had a 50
hm: output impedance. When I measured the maximum voltage across the LC using a DMM and an oscilliscope, I came up with a frequency of 10.83KHz. Why is there such a large difference in frequency? Without using a network analyzer, what is the best way to measure the resonant frequency? Thanks for your help.
