You have a practical current source that can be modeled as a 15-V ideal source in series with a 1-kΩ source resistor. You need to use your source to drive a 1-kΩ load that requires exactly 3 V across it. Two solutions are provided to you as shown in Figure P2–69. Validate that both meet the requirement, then select the best solution and give the reason for your choice. Consider part count, standard parts, accuracy of meeting the spec, power consumed by the source, etc. Validate your results using Multisim.
