Simple question

  1. Feb 21, 2010 #1
    If you have a phasor that has a negative magnitude (ie -3<38degrees) what is the best presentation. I believed it was just erasing the - sign and adding or subtracting 180degrees. Correct me if wrong

    That's right - just remember the resultant phase angle would lie between +/-180 degrees (or 0 and 360, if that's the way you want to do it) - so you may need to do some modulo arithmetic in some cases.

    you are right
