ÓN PROBLEMS Il 309 PROBLEMS SECTION 8.2 Current Sources 1. Find the voltage V., (with polarity) across the ideal cur- rent source of Fig. 8.93, FIG. 8.93 Problem 1. 2. a. Determine Y for the current source of Fig. 8.94(a) with an internal resistance of 10 kQ. b. The source of part (a) is approximated by an ideal cur- rent source in Fig. 8.94(b) since the source resistance is much larger than the applied load. Determine the resulting voltage Y for Fig. 8.94(b), and compare it to that obtained in part (a). Is the use of the ideal current source a good approximation? 20 20 MW — + + 1Ú 4A R Lio xo Say ¡a ía 10) (0) FIG. 8.94 Problem 2. 3. For the network of Fig. 8.95: Ro a. Find the currents /, and /,.
