Day 23 (Apparent Power and Power Factor Lab)

We started the day by deriving the equation for the effective current from power.

We then went and derived what the effective voltage of a sinusoidal voltage source would be.

We then did an example of power with complex and real powers and a power factor that determines what is real and what is complex.

We did another example of complex and real power but this time instead of being given a circuit, we were given RMS polar values for the voltage and current.

We did one final example of apparent power.

We then started the Apparent Power and Power Factor Lab. Here is a picture of the pre-lab.

Here is a picture of the circuit we built.

Here is a picture of the window from the oscilliscope.

Here is a picture of the results of the experimental values.
