Given two batteries: one with voltage V and internal resistance r₁; another with also voltage V and internal resistance r2. Which of the following is true if we connect them in series facing the same direction? The total voltage will be 2V while the total internal resistance will be r₁ + 12. The answer cannot be found on the other choices. No voltage will remain while the total internal resistance will be r₁ + 12. The total voltage will be V, while the total internal resistance will be r₁ + 12.
