EEET2249 Tut-4 1 of 3 EEET2249 Circuit Theory Tutorial-4: Node Voltage Analysis Q1: Calculate the node voltages of the circuit shown in Fig.Q1. Hence determine the total power loss in the resistors. (Ans: -9 V, 3 V, 48 W) Q2: Calculate the node voltages of the circuit shown in Fig.Q2. Hence, calculate the power supplied by the two sources. (Ans: 2 V, 30 V, 24 V, P 5A = 110 W, P 10A = 300 W) Q3: Calculate the node voltages of the circuit shown in Fig.Q3. Hence, calculate the power supplied by the source and the power absorbed by each resistor. (Ans: 3 V, 5 V, 2 V, P 6A = 30 W, 4.5 W, 0.5 W, 12.5 W, 4.5 W, 4 W, 4 W) Circuits with current and voltage sources Q4: Determine the node voltages. Hence, calculate the power supplied by the two sources and the power absorbed by the three resistors in Fig.Q4. (Ans: 3 V, 4.5 V, 2 V, P 3V =-1.5 W , P 1A = 4.5 W, P 3 Ω = 0.75 W, P 5 Ω = 1.25 W, Fig.Q1 9 Ω 3 Ω 4 A 4 Ω 5 A 2 Ω Fig.Q2 4 Ω 1 Ω 3 Ω 10 A Fig.Q3 2 Ω 2 Ω 1 Ω 1 Ω 6 A 2 Ω 2 Ω Fig.Q4 5 Ω 3 Ω 4 Ω 1 A 3 V - +

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
