1. The problem statement, all variables and given/known data (a) Determine the currents I1, I2, I3 in the figure. Assume the internal resistance of each batter is r = 1.0 olms (b) What is the terminal voltage of the 6.0 V battery? I hope you can read my handwriting. 2. Relevant equations V = IR 3. The attempt at a solution I1 + I2 = I3 I don't understand kirchhoff's rules and how the internal resistance of each batter means.
