Calculating Resonance Frequency and Amplitude in RLC Circuits

Click For Summary
An experiment using an RLC circuit aimed to determine resonance frequency and amplitude, yielding a maximum amplitude of 21.5V at 16kHz with an input of 8V. The discussion focused on comparing experimental data to theoretical calculations, with participants sharing formulas for resonance frequency and amplitude. Issues arose regarding discrepancies in amplitude values and the shape of response curves, prompting discussions about impedance and measurement techniques. Adjustments to the capacitance value were suggested, as incorrect capacitance could significantly affect resonance frequency and peak voltage. The conversation highlighted the importance of accurate component values and measurement methods in circuit experiments.

I'm trying to add this part to my lab now. I now assume that 0.0015 µF and 8V peak to peak rather than RMS. I don't see however how you find the values, because when I plug the new variable values in the previous equation I don't get what you posted.

Hmm. If you go to the Excel workbook that I posted and change the capacitance and voltage, how does the plot look?

It works fine now, was changing the wrong variable. Definetly one of the more confusing labs I did... but I learned a lot from it mainly thanks to you! :smile:

No problem. I enjoyed it, too.:smile:

Good luck.
