Rectangular form. This method is also known as symbolic notation. In this method, the phasor is resolved into horizontal and vertical components and is expressed in the complex form as discussed in Art. Consider a voltage phasor V displaced θ CCW from the reference axis (i.e. OX-axis) as shown in Fig. (a). The horizontal or in-phase component of this phasor is a while the vertical or quadrature component is b. Therefore, the phasor can be represented in the rectangular formas:
(a) (b) Fig. (b) shows the phasors in the various quadrants. The phasors have been resolved into horizontal and vertical components. The various phasors can be represented in the rectangular form as : The magnitude and phase angles of these phasors can be found out as explained above. Remember phase angles are to be measured from the reference axis i.e. OX-axis. If the angle is measured CCW from this reference axis, it is assigned a + ve sign. If the angle is measured clockwise from the reference axis, it is assigned a ve sign | |
