This lab assignment emphasizes the use of apparent power and power factor to quantity the AC power delivered to a load and power dissipated by the process of transmitting this power.
In this lab, we are going to provide average power to load power when the power is delivery processing.
We used a 10 ohm resistor, and use it to series with a 1mH inductor and three different resistor (10 ohm, 47 ohm, or 100 ohm) at three different times. and the resistor to be the load.
When a sinusoidal wave with (1cos(2pi*5000t) in the circuit, and we calculate the power dissipated by the resistor.
The is set up
The resistors: 10ohm 47ohm 100ohm
11.9ohm 48.6ohm 99.8ohm
The results and calculations.
When we used different resistor, we measured the voltage of the load and the voltage across the resistor in series.
The oscilloscope screen with 11.9 ohm resistor
The oscilloscope screen with 48.6 ohm resistor
The oscilloscope screen with 99.8 ohm resistor
When the phase difference are very big, we measured the value.
When the capacitor and resistor are in parallel, the voltages is measured.

The phase angles are very small nd less than 3 degrees for each.
