MAE 3780 MECHATRONICS FALL 2009 1 HOMEWORK 2 DUE: 9/14/08 PROBLEMS: Note: you may use Matlab to solve these problems, once you have the system of equations set up. 1. Use node voltage analysis to calculate the current i provided by the voltage source in the circuit shown in Figure 1. You are given the values R 1 = 0.5 , R 2 = 0.5 , R 3 = 0.25 , R 4 = 0.5 , R 5 = 0.25 , V s = 3 V, I s = 0.5 A. Figure 1 2. Use mesh current analysis to calculate the voltage V A across the current source in the circuit shown in Figure 2. Figure 2

MAE 3780 MECHATRONICS FALL 2009 2 3. Use mesh and/or node analysis to determine the power dissipated in resistors 1, 3 and 4. Given R1=R2= 1 k , and R2=R3=2 k and that V1=V3=5 V and V2=10. Figure 3 4. The voltage supply V s in the circuit shown in Figure 4 is nominally a 6 V supply. However, occasionally it “acts up” and produces much larger and smaller voltages than desired. A fuse is inserted in series with the supply in order to protect the rest of the circuit from these surges. This
