# Phasor Diagram

**Phasor Diagram**. Move the sliders to change the amplitude. Phasor diagrams hands-on relay school WSU - pullman, wa.

Phasor diagrams are a way of representing sinusoidal waveforms such that you can add and subtract them and get correct answers. The phasor diagram is a very significant factor of the power system analysis. This Demonstration shows the equivalent circuit phasor diagram for a transformer A power source supplies a voltage that is For , the phasor diagram would be a unit vector rotating about the origin.

### Phasor Diagrams are used in Electrical Engineering to represent the relationship of different AC signals at an instant of time.

Phasors are to AC circuit quantities as polarity is to DC circuit quantities: a way to express the Phasors are based on the concept of complex numbers: combinations of "real" and "imaginary".

Before variables were either "known" or "unknown." Now there is a sort of in between. Phasor Diagram of a Sinusoidal Waveform. A phasor diagram is used to show the phase relationships between two or more sine waves having the same frequency.
