Addition and Subtraction of Phasors The rectangular form is best suited for addition or subtraction of phasors. If the phasors are given in polar form, they should be first converted into rectangular form. Once the phasors are in rectangular form, the in-phase components and the quadrature components can be algebraically added or subtracted. The answer (sum or difference) can be left in rectangular form or it can be converted back to polar form if desired. (i) Addition. For the addition of phasors in the rectangular form, the in-phase components are *added together and the quadrature components are added together. Consider two voltage phasors represented as Fig (a) shows graphically ,the addition of two phasors V1 and V2 in rectangular form. (a) (b) (ii) Subtraction. Like addition, the subtraction of phasors is done by using ordinary rules of phasor algebra Fig. (b) shows graphically the phasor difference of phasors V1 and V2 in rectangular form. | |
