1. The problem statement, all variables and given/known data A battery has a current of 3.0A flow through it. It has an internal resistance of 0.039Ω and the circuit has a load of 45Ω. a) What is the emf? b) What is the voltage that flows? 2. Relevant equations V = ε - IR 3. The attempt at a solution ε = V + IR ε = (45Ω)(3A) + (3A)(0.039Ω) ε = 135V + 0.117V a) 135.117V b) 135V I'm new to emf. Does this look correct? If not, can you explain where I went awry?
