# How many people would it take to run a 2.00 kW electric clothes dryer?

## A person in good physical condition can put out 100 W of useful power for several hours at a stretch, perhaps by pedaling a mechanism that drives an electric generator. Neglecting any problems of generator efficiency and practical considerations such as resting time, answer the following.

$20$?

#### Explanation:

$1 k W = 1000 W$

Therefore, it takes $2 \cdot 1000 = 2000 W$ to run an electric clothes dryer.

One person can put $100 W$ according to the question.

So it takes,

$\frac{2000}{100} = 20$ people to run an electric clothes dryer
