A sinusoidal voltage with 50Hz frequency has the following f

A sinusoidal voltage with 50Hz frequency has the following form: v1(t) = 52 cos(314t 0.96) volts. (Note the minus sign) If this voltage is represented by a phasor, V1, what is the value of the imaginary part of V1, in volts? (Do not include \"j\" in your answer - the answer is only a number)

Solution

v1(t)=50*cos(314t-0.96) volts

v1(t)=50*sin(314t+90-0.96)=50*sin(314t+89.04) volts=50<89.04 volts

convert 50<89.04 in to rectangular form

50<89.04=0.8377188
