The e.m.f. of a cell is 6 volt. When 2 ampere current is drawn from it then th e potential difference across its terminal remains 3 volt. Its internal resistance.

Explanation

To find the internal resistance of the cell, we can use the following steps:

### Step-by-Step Solution:

1. **Identify Given Values**:
- E.M.F. of the cell (E) = 6 volts
- Current drawn (I) = 2 amperes
- Terminal potential difference (V) = 3 volts
