Unformatted text preview: ECTE172 Introduction to Circuits and Devices Spring 2007 Tutorial 2 Numbers within [ ] refer to problems in your recommended text- book: Introductory Circuit Analysis, Boylestad, 11th Edition. Following is only a minimum number of selected problems. You are highly encouraged to attempt and complete other problems from Chapters 5 — 7. 1 10. 11. . [5—10) For each network in Fig 5.94, determine (a) current I (b) source volt-age E (c) unknown resistance (d) voltage across each element. . (5—17) Combine the series voltage sources in Fig. 5.10] into a single voltage source between points a and b. [5—34) (a) Design the circuit- in Fig. 5.117 such that V32 2 3Vgl and V33 2 41/32 [5—35) Determine the voltages 14;, it?” 143:, for the networks in Fig. 5.118. (6—9] Determine R1 for the network in Fig. 6.80. [6—30) Determine the currents for the configurations in Fig. 6.100. [6—38) For the network in Fig. 6.108 determine {a} Is and Vi (b) I; if R]; is short-ed out- (c) VL if BL is replaced with an open circuit. . (7—8) For the series—parallel configuration in Fig. 7.68 find (a) the source current I; {b} currents Is ,1}. {c} current I3 {d} voltage Kb.
