To solve the problem, we need to determine how many cells are wrongly connected in a series of 12 cells, given the current readings when the cells are aiding and opposing the battery. ### Step-by-Step Solution: 1. **Define Variables**: - Let \( n \) be the number of wrongly connected cells. - The total number of cells is 12, so the number of correctly connected cells is \( 12 - n \). ...
