Question

1. Construct to scale a phasor diagram like the one shown in Figure 4 for each of the two cases. Use one sheet of paper and make two separate diagrams on the one sheet. Choose a scale (for example, 1.00 v/cm) so that the diagrams are as large as possible, but that each one fits on one- fourth of the sheet of paper. First construct a vector along the x axis with a length scaled to the magnitude of Va, as shown in Figure 4. Use a compass to construct an arc from the end of V with a radius the length of the scaled value of Vind. Finally, construct an arc from the beginning of Va with a radius the length of the scaled value of V. The intersection of the two arcs is the intersection of Vne and V, and those two vectors can then be drawn in their proper direction as shown in part (b) of the figure. Finally, Vi and V, can be constructed as shown in part (c) of the figure by dropping a perpendicular line from the intersection of the arcs to the x-axis and extending a vector from the end of VR.
