While I was converting this with the inverse phasor transform, I wanna ask a question
P{ -4 cos(200t – 45°)}
Should I say -4∠-45 or 4∠-45 ?
I mean, do I have to preserve the negativity of the magnitude which is "4"?
As far as I have known that the magnitude is not a vectorial thing and then we are supposed to demonstrate it with always positive.
