Unformatted text preview: Figure 5 9. For figure 6, draw the phasor diagram representing all the voltages in the circuit. Figure 6 10. Figure 7 below explains the concept of a non-ideal inductor that includes winding resistance. Study this figure and then refer to figure 8 to draw the power triangle for the circuit in figure 8.
