1. The problem statement, all variables and given/known data Given the following circuit: What is the actual voltage provided to the circuit by the non-ideal battery if the internal resistance r = 0.50 ohms and the internal emf is 9.0 volts? A. 9.8 V B. 8.5 V C. 9.0 V D. 8.4 V E. 8.8 V 2. Relevant equations V=IR 3. The attempt at a solution First, do I determine the current in the circuit, I? Then, Total resistance in circuit if battery was ideal = 9/I 9/I - .5= 9/I-.5 ohms. At I amps, the voltage would be (I amps x 9/I-.5) = how ever many V... How do I calculate I?
