BME 271, HW #3
1. Problem 4.22 of Nilsson and Riedel. 10th ed. Find Vo and the power delivered by the
current source using the Node-voltage technique again.
a. Use node a as the reference node.
b. Repeat part (a) but use node “b” as the reference node.
c. Solve this circuit once again but this time using the Mesh-current technique.
2. Nielssen and Riedel, 10th ed, problem 4.48. Use the mesh-current method to determine
which sources in the circuit below are generating power. Check your answers using a
power balance.
3. Nielssen and Riedel, 10th ed, problem 4.52. Use the mesh-current method to find the
branch currents ia – ie in the circuit below.
4. Nielssen and Riedel, 10th ed, problem 4.62.
a. Use a series of source transformation to find i0 in the circuit below.
b. Verify your solution by using the mesh-current method.
5. Nielssen and Riedel, 10th ed, problem 4.67. Find the Thevenin equivalent circuit with the respect
to the terminals a,b for the circuit below:
6. Nielssen and Riedel, 10th ed, problem 4.69. A Thevenin equivalent of a circuit composed of a
linear resistive elements and independent and dependent sources can be determined from
measurements made at the output terminals of interest. Assume the following measurements
were made at the output terminals a,b:
• When a 20 ohm resistor is connected to the terminals a,b and the voltage across this
resistor, Vab, is found to be 100 V.
• When a 50 ohm resistor is connected to the terminals a,b and the voltage Vab is found to be
200 V.
Find the Thevenin equivalent of the circuit network with respect to terminal a, b using these two
measurements.
7. Nielssen and Riedel, 10th ed, problem 4.75. Find the Norton Equivalent to the terminals
a, b for the circuit below.
