Homework #4. Mesh Analysis

• Read Sections 3.4 to 3.9 of Alexander & Sadiku's Fundamentals of Circuit Analysis (6th edition).
• Make sure you understand the answers to Review Questions 3.1 to 3.8 on pages 111-112. Quiz questions will be similar to these Review Questions or Review Questions from earlier chapters.
• Turn in solutions to Problems 3.35*, 3.36**, 3.37***, 3.44, 3.51, and 3.56 on pages 117 to 124.
• *Typo in the book's answer to Problem 3.35: The answer should be -60 V instead of 20 V.
• **In Problem 3.36, the authors do not follow the convention that they used in this chapter of labeling mesh currents with lowercase i and looping arrows, while labeling branch currents with uppercase I and straight arrows. I recommend that you redraw the diagram using Ia, Ib, and Ic for the three branch currents shown in the diagram, so that you won't confuse these currents with your mesh currents, which you should call i1 and i2.
• ***Don't be scared by the dependent voltage source in Problem 3.37. This source's voltage is 5vo, where vo is the voltage across the 4-Ω resistor. So simply use Ohm's law to rewrite 5vo as 5 times that resistor's current times its resistance.
