## Explained the Diagram of Phasor

A rotating AC voltage current shows the relationship of electrical signal. A phasor quantity represented by the rotating arrow onto the vertical axis. The vertical line or bar represents the value proportional to the sine of the product of the angular frequency for instantaneous value. A signal of the oscilloscope represent ted in the phasor diagram is running sinusoid wave.

## Phasor Diagrams Explained in One Wave

In a phasor diagram explained in one wave, a power source can be supplied to the voltage either in a sine wave of a particular frequency and it can be considered to be the sum of sine waves of different frequencies. It can be directly related to vector length. An angular velocity  with revolving vector length A. At angle t = 0, a phase constant is .

V(t) = Asin( t + ## Phasor Diagrams Explained in Two Waves

One wave can be leading or lagging the other wave, in which the revolving vector of blue is leading the red revolving vector. Likewise, the red vector is lagging the blue vector.

By using algebraic and trigonometric manipulation, adding and subtracting two sine waves.

A Simple Problem of vector Addition:

A sin( t + φ )  = 6 sin(t + 400) + 3 sin ( t + 1200) Regards
