Lab Day 23

Apparent and Power Factor Lab

The purpose of this lab was 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 pre-lab we calculated the theoretical values of the circuit: Current, Voltage, Average Power, Apparent Power, and Power Factor.

For this circuit we will change RT values. All of the circuits will have the same input of 1V at 5Khz.

Here is the output of circuit at RT=47 Ohm.

For second part of lab we insert a 10 microF capacitor in parallel with Inductor and RL. Here is the output of circuit with input of 1V at 5Khz,

According to our experiment, higher RT value results in higher percent difference with theoretical value. However, with capacitor inserted into the circuit, the percent difference is lowered drastically.
