Exam #2 Prep Questions a) Use the Figures at the end of this document to answer the following questions. 1. Calculate the power dissipated by each resistor in Figure 1 when R1 = 2 , R2=5 , R3=10 , R4=8 , R5=3 , V1=4V, V2=2V, and I1=2A. (Ignore the 1K resistor value on the diagram for R1. R1=2 Ω). Resistor Power 2 74.4W 10 .1W 5 5W 8 6.5W 3 1.3W 2. Calculate the power being delivered by the each voltage and current source in Figure 2 when R1 = 6 , R2=4 , R3=5 , R4=15 , R5=3 , R6=2 , V1=10V, I1=2.5A, and I2=4A. Source Power Delivering/Absorbing 10V -65W Delivering 2.5A -23.75W Delivering 4A -134W Delivering 3. Calculate the power being delivered by each current source in Figure 3 when I1=2mA, I2 = 5mA, R1=500 , R2=2k , R3=6k , R4=5k , R5=1.5k , and R6=7k , R7=1k Source Power Delivering/Absorbing 5mA -121mW Delivering 2mA -54.8mW Delivering 4. Using Figure 4 , find the power delivered or supplied by the 10V source using a series of source transformations. (R1=30K , R2=30K , R3=15K , R4=R5=1.5K , R6=13K ). P 10V = -8.5mW (delivering) 5. Find the power absorbed by each resistor in Figure 6 . Resistor Power 10 0W 40 160W 20 80W

Exam #2 Prep Questions 6. Using a series of source transformations, find the power dissipated in the 40 resistor in Figure 6 . P 40 = 160W 7. Prove that power is conserved in Figure 7 when V1=20V, V2=40V, V3=10V, R1=1 , R2=2 , R3=2 , and R4=4 . W 400 P P absorbed delivered = = 8. Find the power dissipated in R4 in Figure 7 when V1=20V, V2=40V, V3=10V, R1=1 , R2=2 , R3=2 , and R4=4 . Use a source transformation approach to
