Day 27 - Thursday, May 26, 2015 - Apparent Power and Power Factor

Today we learned about apparent power and the power factor. l

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.

So the power factor is equal to the cos (theta v - theta i).

Then we did an exercise:

Then we looked at complex power.

Today's lab was called Apparent Power and Power Factor. In it, we calculated the apparent power and measured it.

For our pre-lab, we calculated a few things about our circuit. These are:

And we did so, for three different values of resistors:

For R= 10.4

R = 46.8

R= 99.6

R = 10.4

R= 46.8

R= 99.6
