A car battery has an internal resistance of $0.10\,\Omega$ and an electromotive force of $12\,\text{V}$. Once the battery is linked to the starter motor, the potential difference between the battery terminals is $7.0\,\text{V}$. What is the current supplied to the starter motor?
- A$50\,\text{A}$
- B$70\,\text{A}$
- C$120\,\text{A}$
- D$190\,\text{A}$
