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?
