75. The voltage source V, in Fig. 10.78 is chosen such that Ic =1/0 A. (a) Draw a phasor diagram showing V1, V2, V, and Vg. (b) Use the diagram to deter- mine the ratio of V2 to V1. + V, 5+ -j4 0 VR30 j2n V I FIGURE 10.78 77. The circuit of Fig. 10.79 is unfortunately operating differently than specified; the frequency of the current source is only 19 rad/s. Calculate the aetual itor voltage, and compare it to the expected voltage had the circuit been operat- ing correctly. capac- 12 + Ve 15 mF 22 Ssin(20r+12) V 100 mH A 2 sin(19t+45) A 150 mH Figure 1 ll ll
