Q: Where do you use Kilowatt Hour?

Write your answer...

Nope. "Kilowatt" is a rate of using electric energy. The longer you keep usinga kilowatt, the more energy you'll use, and the higher your electric bill will be.The unit of energy that appears on your bill is the "kilowatt-hour". It mightsurprise you to learn that the kilowatt-hour is the amount of energy you useif you use energy at the rate of one kilowatt and you keep it up for one hour.

Anything that uses 40 kilowatts would use 40 kilowatt-hours for each and every hour.

A kilowatt is a unit of power, while a kilowatt hour is a unit of energy. Power is the rate that energy is used. This means that something that operates at 1 kilowatt for 1 hour uses 1 kilowatt hour of energy.

The energy 1 kilowatt-hour (kWh) is 3600000 joules.AnswerThere is no such thing as a 'kilowatt per hour'. You probably mean 'kilowatt hour'?

Kilowatt is a measure of the rate of energy use. It is 1,000 Watts or 1,000 Joules per second. A kilowatt hour is 1,000 Joules per second for 3,600 seconds or 3,600,000 Joules. This means a Kilowatt hour not a rate but a measure of total energy used.

There are 60 minutes in a kilowatt hour. an hour is 60 minutes, a kilowatt is a rate of power usage.

One kilowatt-hour is 3.6 million joules.

Watts does not have a time component to it; so you should have asked, "How many kilowatt-hours does an oven use per hour?' For example, if the oven uses 1600 watts, then in one hour, it would use 1600 watt-hours, or 1.6 kilowatt-hours.

Well 1 KWh is "1000 watts per hour". So if you have 400w per hour take400watts per hour divided by 1000 and it shows that you get "0.4KWh".AnswerThere is no such thing as a 'kilowatt per hour', which is why the unit of measurement is a 'kilowatt hour', and NOT a 'kilowatt per hour'!.To determine the number of kilowatt hours of energy consumed by the lamp, multiply its power, expressed in kilowatts, by the length of time it is in use. For your example, the answer is 0.4 kWh.

It is a unit of energy. If energy is transferred at a rate (power) of one kilowatt, during one hour, then one kilowatt-hour (kilowatt times hour) of energy will be transferred. Since a joule is equal to a watt-second, a kilowatt-hour is the same as 3.6 million joules.

There is no such thing as a "kilowatt per hour". Kilowatt is a unit of power, not of energy. A unit of energy is kilowatt-hour. That's kilowatt times hours, not "per" hour ("per" implies division, not multiplication). If a generator produces 10 kilowatts, that means it produces 10 kilowatt-hours every hour.

A 400-watt light uses energy at the rate of 0.4 kilowatt. In 1 hour, it uses 0.4 kilowatt-hour of energy.

kilowatt hour - the use of 1000 watts in one hour

Another name for kilowatt hour don't exist.

The kilowatt-hour is a unit of energy. The basic metric unit of energy is the Joule. If you use energy at the rate of 1 Joule per second, you are using '1 watt' of power. If you use 1,000 Joules per second, you're using '1 kilowatt' of power. If you keep it up for an hour (3,600 seconds), you've used a total of 3,600,000 Joules of energy. The other ways to express that amount of energy are: 3,600,000 watt-seconds 3,600 kilowatt-seconds 1 kilowatt-hour.

A Kilowatt hour is 1000 watts per hour. A 50 watt bulb will use just 50 watts per hour. Therefore over 12 hours the 50 watt bulb will use 50*12 watts = 600 watts or 0.6 of a kilowatt hour.

2.8 cents per kilowatt hour

A kilowatt hour meter (or more common called electricity meter) is an instrument to measure the consumed quantity of kilowatt hours.

KwH

A unit (as mentioned on the electricity bills) is represented in kWH or Kilowatt Hour. This is the actual electricity or energy used. If you use 1000 Watts or 1 Kilowatt of power for 1 hour then you consume 1 unit or 1 Kilowatt-Hour (kWH) of electricity.

The kilowatt hour (KWHr) measures electricity use.

all inclusive, use 10 cents for any estimates and you are good to go. one kilowatt hour will run a 1hp electric motor or 17 60 watts light bulbs for one hour. OR 1 kwh is enough to leave one light bulb on for 17 hours.AnswerYou are not charged by the kilowatt (power) but by the kilowatt hour (energy). Check with your electricity supply company to find out how much they charge per kilowatt hour.

A power of 1000 watts is one kilowatt, so in one hour the energy used is one kilowatt-hour, also known as one Unit.

Electricity usage is measured in kilowatt/hours. To put this in perspective, a 1500 watt kettle that is on constantly for one hour would use 1.5 kilowatts. Multiply that by the cost per kilowatt hour will give you the operating cost of your appliance. On your electrical bill the rate per kilowatt hour should be stated. It could be in the range of .07 to .10 cents per kilowatt hour.

Pretty much, just one. Your 100 watt lightbulb uses one tenth of a kilowatt every hour. Ten light bulbs on use 1 kilowatt of power in one hour. When your water heater runs, it takes about 20 minutes to use 1 kilowatt. One kilowatt goes quick and is nothing. At around 10 cents per kilowatt, it takes a while for your power bill to add up.
