Phasor Math General Information


The Phasor Math pages allow you to perform basic phasor operations, as originally conceived by Charles Proteus Steinmetz, renowned physicist and electrical engineer of the early 20th century. Operations include adding, subtracting, multiplying, and dividing phasors. Impedance or admittance may be expressed as a phasor and the tools provided in these pages allow you to perform addition of the same, as well as differential voltage or current and power phasor calculations.


Numeric values may be entered conventionally with a decimal point for a real (non-integer) quantity. Optionally, scientific notation may be used, where "e" or "E" is recognized as the decimal radix. For example, the number -123456.789 may be entered as -1.23456789e5.


The magnitude of any operation is internally computed with the maximum accuracy available for the host processor and, unless otherwise indicated, the displayed result reflects this. Notice that a computed angle is normalized so that its magnitude is always less than 360. For example, a computed angle of 720 degrees is normalized to 0 degrees.


If your browser supports web storage, three separate phasors may be stored and recalled with associated buttons.
