(1) Capacitor (unknown value) Experiment Setup The purpose of this lab is to estimate the capacitance of capacitor from a time domain using an oscilloscope. The oscilloscope is an instrument used for viewing and measuring time varying signals. The function generator was implemented so as to output standard test signals such as sinusoidal, square and triangular wave graph.

Figure 2: Basic circuit for the experiment Part A: Procedure: I. First of all , the function generator was configured to output a nearly 1.88V peak to peak sinusoidal wave with frequency of 1.006 kHz and 0V DC offset. II. We used the Channel 1 of the oscilloscope to measure the signal from the function generator while making sure the oscilloscope probe is configured with the x1 setting and the attenuation calibration on the oscilloscope is set to x1. III. The time base was adjusted in such way that a few periods of the sinusoidal waveform was visible on the screen . Also, the Channel 1 volts/ division adjustment was adjusted until the sinusoidal waveform fills up most of the oscilloscope screen and made sure that the center of the trace on the screen using the vertical position control for Channel 1 .
