Phasors: Passive RL Circuit Response

 This is basic understanding of phasors. On the board, we derived how to look at phasors.

This was an activity to determine the difference between two phasors.

 These are all the different forms in which a phasor could be existent.

 On the left, we see all the rules for phasor calculation. On the right are all the examples of phasor calculations.

 In this example, we solved a phasor equation, then reconverted it to a time-dependent voltage. The magnitude of the voltage goes in front of the cosine function. The phase angle goes inside the cosine function, after the time.

 In these examples, we add together two voltages by solving them in the phasor domain and converting them to the time-dependent domain. We take the answer and solve for current in time-dependent domain.

 This is the pre-lab in which we find the frequency, the gain, and the cutoff using the phasor domain we just learned.

 This was the first frequency found at 70K hz.

This was the built circuit for phasors.
