RMS and AC Current and Voltage
For our first experiment we connected a 220µF capacitor in series with a function generator that was feeding a 10Hz sinusoidal wave into the circuit.
The above pictured image is the result of the data collected from the AC Circuit. It is clear that the current and voltage are sinusoidal and that there is a phase shift between the two graphs.
After testing the circuit at 10Hz we doubled the frequency to 20Hz and repeated the experiment. As seen below the graphs again were the same just with a difference in phase shift.
Our results for Vmax, Vrms, Imax, Irms, and XC (theoretical and experimental). can be seen below for both experiments.
The next part of this experiment was the same as the first however this time we used an inductor. We repeated all the same steps as for the capacitor and went on to calculate Vmax, Vrms, Imax, Irms, and XL (theoretical and experimental).
The picture above shows the set up for the inductor circuit, however to prevent an over current error we had to connect a 100Ω resistor in series with the circuit. Instead of changing the frequency we took two sets of data without an iron core and with an iron core (small bolt). Our data is shown below.
