Phasor Diagrams?? 1. The problem statement, all variables and given/known data Say I am given this circuit diagram. I have the recorded values on the voltmeter and ammeter. I can verify the power factor rating using these two values. But I also need to draw a phasor diagram for this circuit as well as two others which just have other devices added on. The problem is that I have no idea what is a phasor diagram, my notes don't have anything about it. From what I read online, all usually have something to do with the equation [itex]Asin(\omega t + \phi)[/itex]. I just don't know how to get that equation given what I know.
