To solve the problem, we need to find the relationship between the load resistance \( R \), the internal resistance of the first cell \( r_1 \), and the internal resistance of the second cell \( r_2 \) given that the potential difference across the first cell is zero. ### Step-by-Step Solution: 1. **Understanding the Circuit**: We have two cells (batteries) connected in series, each with an EMF \( E \) and internal resistances \( r_1 \) and \( r_2 \). They are connected across a load resistance \( R \). 2. **Current in the Circuit**: ...
