Apparent Power and Power Factor

 This is a graph of what power output would look like theoretically. We find the power, the current max, the voltage max, and the power max.

 This is an example combining phasors that we learned in the previous class and using them to find the complex power, the apparent power, the real power, the reactive power, and the power factor. he most difficult concept of all of these is the complex power because we are dealing with power in the imaginary part of the phasor.

 In this example, we are once again using the phasor to find the voltage across the inductor. In order to achieve this, we need to put all of the elements in their impedance form; the impedance for inductor is z=jwl. Then we find the apparent power, the average power, and the RMS.

 This is the built circuit for the apparent power lab.

 These are the results with 10 ohms across the resistor and 10 ohms across the inductor.

 These are the results with 10 ohms across the inductor.
