Cartesian Form of Complex Numbers refers to the representation of complex numbers in a 'real + imaginary' structure.
The real part is represented by '' and the imaginary part is represented by '', forming the equation :

To graph an voltage of volts on a complex plane, we plot the real part () on the -axis and the imaginary part () on the -axis, the point (, ) .
Then, connect the point (, ) to the origin (, ) to form the voltage vector.
As you can see, the voltage vector is in Quadrant II.
