Two identical cells each of emf `epsilon`, having negligible internal reistance r, are connercted in parallel with each other across an external resistance R. What is the current through this resistance.

Explanation

To solve the problem, we need to determine the current flowing through the external resistance \( R \) when two identical cells, each with an electromotive force (emf) \( \epsilon \) and negligible internal resistance \( r \), are connected in parallel.

### Step-by-Step Solution:

1. **Identify the Configuration**:
- We have two identical cells connected in parallel. Each cell has an emf \( \epsilon \) and negligible internal resistance \( r \).

2. **Determine the Equivalent EMF**:
