Today we went over apparent power and power factor, and did an Apparent Power and Power Factor Lab to measure a circuit's apparent power and power factor.
To the left we have the equations necessary for solving for apparent power and power factor. To the right we have an example and we find that for inductors, current lags voltage.
Above we see represent real power as P and Q represents imaginary (reactive) power in apparent power.
Apparent Power and Power Factor Lab:
The purpose of this lab is to use apparent power and power factor to quantify the AC power delivered to a load and the power dissipated by the process of transmitting this power.
For the prelab we calculated the theoretical values of the circuit shown in blue for the 10, 47, and 100 ohms.
Our results are displayed in pink and we see that for the 10 ohm resistor and the capacitor included in the circuit we get great within uncertainty. We see that when a capacitor is placed in parallel with an inductor, the phase angle decreases dramatically.
Input wave for all three resistor values.
Output for 10 ohm resistor
Output for 47 ohm resistor
Output for 100 ohm resistor
This is the output was when a capacitor was placed in parallel with the inductor using the 100 ohm resistor.
