Hi is anyone able to help me with this question??
draw to scale 3 phasors representing the following voltages, taking e1 as reference phasor
e1:= 80 sin ωt volts
e2= 60 cos ωt volts
e3 = 100 sin (ωt-∏/3) volts
I think i understand this part, is it 1 sin wave and 1 cosine wave and 1 lagging sin wave on one 2∏ cycle chart,
the part im not sure is it then asks to sum these 3 voltages and express it in the form Em sin (ωt ± θ), i think i can sum the 2 sin waves though i'm unsure, it is the cosine i'm unsure with...
is anyone able to help please
