First, let's draw a typical parallelogram, as shown in Fig. 3, with sides A and B. To find the length of the diagonal line P, we use the following equation: P = ¡Ì [ (A 2 + B 2) - (2AB cos ¦È) ] ...

The vector diagram for this condition (Fig. 3) shows that a portion of the neutral conductor current, as represented by Vector N, results from the vector addition of Vectors A and B. As we've ...
