Abstract (10 pts.) Provide an abstract for this experiment here. In this experiment, we investigated the different ways to determine the time constant RC. By observing the change in voltage over time in two simple circuits of a resistor and a capacitor in parallel, we were able to calculate the time constant. In part 1, a 1000μF capacitor was charged and then a switch was opened to allow the capacitor to discharge through the resistor. The recorded capacitor voltages was graphed using natural logs in order to solve for the time constant RC in the equation Vc = Vo e^(-t/RC). The predicted value of the time constant disagreed with the experimental time constant of 101+/-2 seconds because a capacitance meter was not provided for us to use in the laboratory and therefore the capacitor’s properties were assumed to be as stated by the manufacturer. In part 2, we used an oscilloscope in order to determine the time constant. The time constant provided by the oscilloscope of 7 +/-1μs overlapped the uncertainty of the predicted time constant. Data, Results, Graphs 1. Make a graph of Vc vs. t for the data obtained in Part 1. Add an exponential trendline to the plot. JPG/GIF files only. 2. Now make a graph of ln(Vc/Vo) vs. t for the same data, and include a least- squares linear fit. JPG/GIF files only. Numerical Results
