May 5 Class Lab


We have an Alternating Current circuit and applied signal to alter its image. 




We attempted to calculate the value for the capacitor


Notice:
Frequency vs. Voltage
30Hz - 2V
40Hz - 1.84V
50Hz - 1.68 V
60Hz - 1.54V
70Hz - 1.40V
80Hz - 1.28V
90Hz - 1.18V
Not a linear relationship
A larger value for frequency makes the voltage drop (a 1/f ratio almost).
Applying a 100Hz would result in a 1.08V and cause a phase shift
We resulted  with a  sinusoidal wave that changed its appearance as frequency was increased
There comes a point where the capacitor begins to act like a short circuit
