5-26: Apparent Power and Power factor

This lab is about power and power factor to quantity the AC power delivered to a load and power dissipated by the process of transmitting this power

This the formula for the power factor. The apparent power is denoted S and it is the product of V rms and I rms. We can also describe the average power as the product of the power factor and the apparent power.

Pre-lab, we used the R2 at different value to get the theoretical values.

Follow the handout, the circuit we build for this lab

The oscilloscope screen with 10 ohm resistor

The oscilloscope screen with 47 ohm resistor.

The oscilloscope screen with 100 ohm resistor

the oscilloscope screen with 10 ohm resistor with a capacitor

the oscilloscope screen with 47 ohm resistor with a capacitor

the oscilloscope screen with 100 ohm resistor with a capacitor

when we add a capacitor in series with resistor. 

For this lab, we learned about apparent power and power factor. and we can  add a capacitor to reduce the phase shift  it could increase the apparent power.
