How many watts are used during 1 kilowatt hour?

Question

I need to find this out.

Answer 1

unanswerable question.

Watts are a rate of using energy, kW-hr is a unit of energy.

You can use 1 watt for 1000 hours and get 1 kW-hr

or 1000 watts for 1 hour to get 1 kW-hr also.

or any numbers in between.

.

Answer 2

Trick question. You don't "use" watts, you use energy. Watts are the *rate* of usage of energy. The kilowatt-hour is the energy itself. (One watt-second = 1 joule of energy, one watt-hour is 3600 J.)

Knowing that kwh = (W/1000) * t, then it follows that (W/1000) and t can take on almost any values so long as their product is 1.

If you know t, then you can compute W. So if t = one hour, then W = 1000 = 1 kW.

Answer 3

It can be 1000 watt for one hour, or 3.6 megawatt for 1 second, or anything that multiplies power and time to give 3.6 million watt-second. A watt-hour is a measure of energy, a watt is a measure of power (equal to one joule per second).
