If V1 = 2sin(2 pi ft), and V2 with a RMS voltage of 5V is leading V1 by 30o, and V3 with a peak to peak voltage of 8V is lagging V2 by 60o, then a) Draw the phasor diagram for V1, V2 and V3. b) Find out the value of V1+V2-V3 and draw the phasor diagram for it. c) If the frequency of all signals is 60Hz, then what is the angular position V1 and v2 and v3 at 10th second?
