A car battery with a 12V e.m.f. and an internal resistance of 0.04`Omega` is being charged with a current of 50A.
The potential difference V across the terminals of the battery are:

Options

A. 10V
B. 12V
C. 14V
D. 16V

Explanation

To find the potential difference \( V \) across the terminals of a car battery being charged, we can follow these steps:

### Step-by-Step Solution:

1. **Identify Given Values:**
- Electromotive force (e.m.f) of the battery, \( E = 12 \, \text{V} \)
- Internal resistance of the battery, \( r = 0.04 \, \Omega \)
- Charging current, \( I = 50 \, \text{A} \)
