A battery of e.m.f 6 V and internal resistance `1 Omega` gives a p.d of 5.8 V when connected to a resistance . Find the external resistance .

Explanation

To solve the problem step by step, we will use the information provided in the question and apply Ohm's law and the concept of internal resistance in a circuit.

### Step-by-Step Solution:

1. **Identify the given values:**
- Electromotive force (e) = 6 V
- Internal resistance (r) = 1 Ω
- Potential difference across the terminals (V) = 5.8 V
