A motor has to be operated at a distance of $800\,\text{m}$ from its power supply. For it to work, the motor needs a potential difference (p.d.) of $16.0\,\text{V}$ and a current of $0.60\,\text{A}$. As shown, two wires are used to deliver power to the motor. Each wire has a resistance of $0.0050\,\Omega$ per metre. What minimum output p.d. must the power supply provide?
- A$11.2\,\text{V}$
- B$16.0\,\text{V}$
- C$18.4\,\text{V}$
- D$20.8\,\text{V}$
