1. Show that the Thvenin and Norton equivalent circuits are indistinguishable (from the outside at the terminals). Background: Any linear component can be modeled as either An imperfect current source: an ideal current source with a resistance in parallel (a Norton equivalent circuit), or An imperfect voltage source: an ideal voltage source with a resistance in series (a Thvenin equivalent circuit). If all we can do is measure terminal voltage and output current under various loads and cannot measure anything inside the model, shown within the dashed box, there is no way to distinguish which one is the more appropriate model of the component. Problem: a. Show that the same measured voltage is obtained if the load is an ideal voltmeter. b. Show that the same measured current is obtained if the load is an ideal ammeter. c. Show that the same output power is obtained if the load is a 100 resistor. d. State in words what is meant by equivalent circuits
