Inverting the amplitude is the same as adding a 180-degree phase shift. To make the rotation direction different, you need a negative sign in a different place...smstepanic said:

A phasor is a vector that represents the magnitude and phase of an alternating current (AC) or voltage. When drawn in a counterclockwise (CCW) direction, it signifies a positive phase angle.
The direction of a phasor is determined by the direction of the alternating current or voltage it represents. In a CCW direction, the phasor will have a positive phase angle, while in a clockwise direction, it will have a negative phase angle.
A phasor going in a CCW direction indicates that the alternating current or voltage is leading the reference signal in a positive direction. This can be useful in analyzing the behavior of AC circuits and understanding the relationship between different components.
No, a phasor can go in both CCW and clockwise directions. The direction of the phasor depends on the direction of the alternating current or voltage it represents.
A phasor going in a CCW direction is represented by a vector in the complex plane, with a positive imaginary component. It can also be represented by a complex number in polar form, with the magnitude as the modulus and the phase angle as the argument.
