Introduction

In this experiment we recoded and measured the resonant frequencies for a resistor, inductor, and capacitor. After, we measured the peak-to-peak voltages at various frequencies across the inductor and the resistor.

Data:

C = 0.01μF, L =23 mHenries ± 10% Total resistance = 100Ω + 7500Ω = 7600Ω

far off. The failures are due to the fact that the equipment wasn’t very precise in measuring the frequencies of these resonances. The largest source of error prominent in this experiment was the random error in measurement from the signal generator. The signal generator’s units of measurement were too limited to obtain consistently accurate frequencies

Conclusion

Unfortunately, the d vs. sigma d comparisons we performed on our data confirmed that the data was not within experimental limits of error. This part was not successful. The experiment gave us a clear understanding of RLC circuit and how it works.
