Chapter 3, Problem 36. Rework Prob. 3.6 using mesh analysis. Chapter 3, Problem 6 Use nodal analysis to obtain v 0 in the circuit in Fig. 3.55. Figure 3.55 Note: ignore the currents shown above and draw new loop currents. Each loop is to be drawn clockwise. Then write the KVL for those loops. Show your work. Once you find the loop current answers, then you must use those currents to find v 0 by following any path from a known voltage and calculating the voltage rises and drops. Ground is a known voltage of 0 volts and the 12 volts on the left is a known voltage.

Chapter 3, Problem 39. Determine the mesh currents i 1 and i 2 in the circuit shown in Fig. 3.85. Figure 3.85
Chapter 3, Problem 40. For the bridge network in Fig. 3.86, find I o using mesh analysis. Figure 3.86 Note – since the bridge is balanced, you can check your answer using parallel and series R combinations to find Req and then use ohm’s law to find i

Use mesh analysis to obtain i o in the circuit of Fig. 3.90. Figure 3.90 IS = I2 + I3 I3-I2 = 3 Io = I2 I1 (look at their directions. I2 is going in the same direction, I1 is going in the opposite direction.) Do it just like #50 Chapter 3, Problem 50. Use mesh analysis to find the current i o in the circuit in Fig. 3.95. Figure 3.95 I1, I3 I2 IS = I3+I2 I3 I2 = 3Io-60 + 10(I2-I1) + 2(I3-I1) + 8I3 = 0 4I+ 2(I1-I3) + 10(I1-I2) = 0 Chapter 3, Problem 52. Use mesh analysis to find i 1 , i 2 , and i 3 in the circuit of Fig. 3.97. Figure 3.97 Vo = 2(I1-I2) 2Vo = 2(2(I1-I2)) = 4(I1-I2) IS = I2 + I3 I3 I2 = 3...
