Introduction The purpose of this lab is to manipulate AC, RC and RL circuits and to analyze all the parameters such as the period, phase angles, and the graphs. Procedure Hardware : - Analog Oscilloscope - AC Function generator - Resistors (10kΩ) - Capacitor(0.1uF) - Inductor (25mH) Experiment : In the first part of the experiment, we set up an RC circuit to a function generator. We then connected two channels of the oscilloscope to the circuit by hooking the first channel to display the voltage signal and the second channel to display the signal across the capacitor. We then triggered the oscilloscope and set up the function generator on a frequency high enough to display the waves forms in such a way that Vr = ½ Vin. We then use the dual trace feature of the oscilloscope to make phase measurements over a sufficiently wide range of frequencies to plot the graph of tan φ vs. 1/ω In the second part of the experiment, we set up an RL circuit by connecting a 25mH inductor in series with a 1kΩ resistor. We then set it and collect a set of data of , to get tan () and In the last part of the experiment, we set up again an RL circuit and record V L and Vr. We then find a frequency high enough so that VL and VR have the same amplitude and verify that
