I'm working on some homework problems and i'm having a lot of trouble with phasors. i have a problem: Determine V and P app when I leads V by 30°. P= 500W and I= 3A. Is current the adjacent (x axis) and power the opposite side to theta (y axis)? I'm having trouble figuring which values go where to make my calculations. Could someone help me oit? I would appreciate it.

You have to get the basics of phasors before you can work these kind of problems. They are vectors which have a magnitude and direction, and there is an angle between them. The cosine of the angle tells the power factor.
