I have these three circuits

(For this one I have readings when the switch was opened and closed)

For this circuits, all I have are the readings on the ammeter(s), voltmeter, resistor, the pf meter (which you have to multiply a reading by a factor to get the apparent power), the inductance and resistance of the inductor, and the values of the capacitors.
I need to draw the phasor diagrams for the three circuits. The only problem is that I do not fully understand them as I was not taught them and I need to hand this assignment in by next week.
I understand that phasors are complex numbers but I don't get how I can use this fact when all the values I have are real numbers.
Also I found the phase difference by finding arccos(power factor), but still don't know what to do with it.
