1. The problem statement, all variables and given/known data Find the terminal voltage across the 16-V battery and 8-V battery. 2. Relevant equations V=IR 3. The attempt at a solution I calculated the total current of the circuit to be 5-A, but after that I'm stuck. What I did (and it was wrong) was simply use the voltage of the battery and subtracted the voltage produced by internal resistance as well as the other resistors. Any guidance would be much appreciated.
