To solve the problem, we need to find the internal resistance \( r \) of each identical cell given that the current through the external resistance of \( 1 \, \Omega \) is the same whether the cells are connected in series or in parallel.
### Step-by-Step Solution:
1. **Define Variables:**
- Let \( \epsilon \) be the emf of each cell.
- Let \( r \) be the internal resistance of each cell.
- The external resistance \( R = 1 \, \Omega \).
