In this lab, we investigated AC signals and the corresponding phase effects on circuit elements. This was achieved by hooking up an AC signal from a function generator into a simple RC circuit and then analyzing the results using an oscilloscope and multimeter. The time difference between the signals was determined on the oscilloscope which was then used to determine the phase difference.
Unfortunately no picture is available.
Data: | |
AC Signal | 3 V peak to peak @ 2 kHz |
Anticipated V RMS | 2.12 V |
Measured V RMS | 2.0 V |
Z C | -j717 ohm |
V C peak to peak | 2 V |
Measured VC RMS | .61 V |
∆t between sign | 90 ms |
phase θ | 199.8 deg |
This phase angle indicates that capacitor signal leads the resistor.
