Enter the real and imaginary numbers of a rectangular form into the phasor calculator. The calculator will return the phasor value of that equation. This calculator can also determine the y or x values given the phasor angle and the other variable.

Phasor Formula

The following formula is used to convert a rectangular form to a phasor form.

P = arctan (y/x)
  • Where P is the phasor angle
  • y is the imaginary part of the rectangular form x + jy
  • x is the real part of the rectangular form

To calculate a phasor angle, take the inverse tangent of the result of the y value divided by the x value of the rectangular form equation.

Phasor Definition

A phasor is defined as the relative angle of a multiple-part solution that contains both a real and imaginary portion.

How to calculate phasor angle?

How to calculate a phasor angle

  1. First, determine the rectangular form

    This will be an equation of the form x + jy, where x is the real part and y is the imaginary part.

  2. Next, separate x and y from the equation in step 1

    Take out the real and imaginary portions.

  3. Calculate the phasor

    Enter the x and y components into the formula above.
