| - | Your $18~{\rm V}$ vacuum cleaner is equipped with a $4.0~{\rm Ah}$ battery, it runs $15~{\rm minutes}$. \\ | ||
| - | How much electrical power is consumed by the motor during this time on average? | ||

| - | \begin{align*} | ||
| - | W &= 18~{\rm V} \cdot 4.0~{\rm Ah} = 72~{\rm Wh} \\ \\ | ||
| - | t &= 15~{\rm min} = 0.25~{\rm h} \\ \\ | ||
| - | |||
| - | P &= {{W } \over {t }} \\ | ||
| - | &= {{72~\rm Wh} \over {0.25~\rm h }} = 288~{\rm W} | ||
