Unformatted text preview: Physics Lab Lab 9 AC Circuits Aleksey Zelenberg Introduction This experiment consisted of two parts. In the first part, we observed the effect of resonance a resonance driving frequency on an AC circuit setup (shown below  Fig 1) at three discrete resistance values. In the second part, we observed and measured the phase shift at various driving frequencies. Our results from the first part indicate that the calculated and theoretical value for the resonance frequencies do not agree within error. Our results from the second part indicate significant percent errors in the phase shift (when compared to the theoretical value). Procedure Fig 1 i Resonance After constructing the circuit shown above with a 50 resistor, a 150 mH inductor, and a 0.5 F capacitor, we varied the function generators frequency to obtain the resonance frequency, . After estimating a value for the resonance frequency, we scanned over a frequency range (in both directions) and obtained the necessary data. We then repeated the stated procedure with a 10 resistor and then a 500 resistor. Finally, to estimate the inductance of a large copper ring, we determined the resonance...
