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 opposite direction? No voltage will remain, while the total internal resistance will be r1 + r2. The total voltage will be -V, while the total internal resistance will be r1 + r2. The total voltage will be -2V, while the total internal resistance will be r1 + r2. The answer can be found on the other choices.
