Its pretty clear that the average power is now zeroweird, since the magnitudes of voltage and current are identical. Where Re (A + B) = x + m is part of the sum of real numbers, And Im(A + B) = y + n is part of sum of imaginary number. The real part is 2 and the imaginary part is 3, so the complex coordinate is (2, 3) where 2 is on the real (or horizontal) axis and 3 is on the imaginary (or vertical) axis. The lengths of the real and imaginary projections are related to the magnitude of the vector cosine and sine of the phase angle respectively.

The angle \varphi is measured from the X-axis counterclockwise, and it can vary from 000 to 22\pi2 or from -\pi to \pi (depending on convention since both are equivalent). Multiplication: (3+2i)*(5-3i). Example: re(2-3i) = 2. im, imaginary part of complex number. The power waveform is identical to that in Figure 1 but shifted down, so it straddles the horizontal axis. Most loads in AC systems will have some resistive and some reactive component, so one number is not enough to describe power in these cases. Complex Numbers | Ultimate Electronics Book The division of complex numbers with this notation is almost the same: A / B = | z_1| * exp (i_1)/ | z^2| * exp (i)= | z_1/z^2| * exp (i(_1 ^2) ),Rewrite the result as: A / B = | z_1 / z^2| and arg (A / B) = _1 ^2. Answer (1 of 2): According to Wikipedia [1], a complex number z can be written as: z = |z| e^{i \phi}\tag{1} Where: |z| is called the absolute value, modulus or magnitude \phi is called the argument or phase All you have to do is substitute the known values of |z|,\phi into (1).
