Two alternating currents are applied out of phase with each other. One is 4 volts and the other is 3 volts 27° out of phase.
These can be written as (4, 0°) and (3, 27°)
a)draw both phasors
b)draw the combined phasor between (0 degree and 360 degree)
c)label peak voltage and state its value
The Attempt at a Solution
a)A rough drawing on paint http://imageshack.us/photo/my-images/3/plotb.jpg/
b) I know A= 6.8106 volts by using this formula
r=3cos27 + 4i + i(3sin 27)
r=√(3cos27 + 9)2 + (3sin27)2
