Quizplus · Accepted Answer

In a Cartesian coordinate system, the horizontal axis represents the real part of a phasor while the vertical axis represents the imaginary part. The reference phasor is usually chosen as the voltage phasor and it is drawn along the horizontal positive axis to represent the voltage source. This convention is widely used in electrical engineering and is referred to as the phasor diagram convention.
