WebPhasors are rotating vectors having the length equal to the peak value of oscillations, and the angular speed equal to the angular frequency of the oscillations. They are helpful in depicting the phase relationships between two or more oscillations. They are also a useful tool to add/subtract oscillations. Created by Mahesh Shenoy.
