A kettle does 1 J of work in 1 second. What is the power of the kettle?

Answers

Answer 1

Answer:

The power of the kettle is P = 1 watt.

Explanation:

The definition of power is:

Power equals the quotient between work and time, or:

P = w/t.

In this case, we know that the work is:

w = 1J

And the time is:

t = 1 s

Then the power will be:

P = 1J/1s = 1 J/s

Also knowing that:

1 J/s = 1 W

(w is the unit for Watt)

We can conclude that the power of the kettle is:

P = 1 W
