Cartesian Form of Complex Numbers refers to the representation of complex numbers in a 'real + imaginary' structure.
The real part is represented by 'x' and the imaginary part is represented by 'iy', forming the equation :
z+=+x+%2B+iy
To graph an AC voltage of -9.8%2B8.9i+volts on a complex plane, we plot the real part (-9.8) on the x-axis and the imaginary part (8.9) on the y-axis, the point (-9.8, 8.9) .
Then, connect the point (-9.8, 8.9) to the origin (0, 0) to form the voltage vector.
As you can see, the voltage vector is in Quadrant II.
