Homework Help: Finding voltage phasor resistance * current phasor

  1. Apr 27, 2013 #1
    1. The problem statement, all variables and given/known data

    I=75<120 deg.
    R= 4k
    find phasor voltage

    does the 4,000 multiply the 75 only so you get


    or does it multiply 4,000 both values including the angle ?

    Multiplying a complex number or phasor by a real constant changes only its magnitude. The angle remains the same.
