To solve the problem, we need to analyze the relationship between the current \( I \) and the number of identical cells \( n \) in a battery when the terminals are short-circuited. ### Step-by-Step Solution: 1. **Understanding the Setup**: - We have a battery made up of \( n \) identical cells connected in series. - Each cell has an electromotive force (EMF) \( E \) and an internal resistance \( r \). - When the terminals are short-circuited, we want to find the current \( I \) flowing through the circuit. ...
