Question

b) Suppose that the power supply is not ideal and to a good approximation can be modeled as an EMF of “E" with an internal resistance of "r". And suppose that r-2.0 Using the values of your theoretical treatment of your resistor network, solve for the value of ε¾ that existed while your resistor network was running. (5 pts) c) Suppose that the power supply is not ideal and to a good approximation can be modeled as an EMF of "" with an internal resistance of "r". And suppose that r- 2.0] What external resistance, "Rex" would you have to attach across the power supply running with ¼ = 10.0[V] so that 10% of the power was dissipated inside the power supply and 90% was dissipated in the external resistor? (Note: this has nothing to do with your resistor network. That is removed and you are just attaching one resistor to the power supply like you did in part 2.) Rex (5 pts) ll uit cireult and relocate the ammeter as shown. Gradually turn ame reading for VA as before (Using voltmeter across the power supply). ble 3.
