A student is comparing four different electric motors. He records how long each motor needs to raise either a heavy load or a light load by a vertical distance of $1\,\text{m}$. He carries out the same measurement for the remaining three motors. The table presents his results. Which motor has the greatest power?
- Aheavy load, time taken $12\,\text{s}$
- Bheavy load, time taken $16\,\text{s}$
- Clight load, time taken $12\,\text{s}$
- Dlight load, time taken $16\,\text{s}$
