Unformatted text preview: cuit makes the current-voltage relation exponential rather than linear like in part I. We confirmed the equivalent resistance of series and parallel resistor circuits experimentally with error less than 0.2%, which is an outstanding success. And in the last part of the DC lab we showed how lowering the temperature of a conductor, in this case copper wire, lowers its resistivity greatly. In part 2 of this lab we measured the voltage output from RC and RL circuits. I chose to analyze the RC circuit further and upon linearizing and applying a regression, I was able to calculate an experimental time constant value that was within 9% of the theoretical time constant, so I consider that fairly successful. In the last section, we analyzed an RLC circuit and collected data somewhat manually using the function generator. We adjusted the frequency until we saw what we believed to be the maximum voltage, which indicates the resonant frequency. When comparing our experimentally found resonant frequency of the circuit to the theoretical one, we ended up with an error under 3%, which I consider incredibly successful....
