What is difference between Kilowatt power vs 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.
How many joules of energy are in 1 kWH?
1 joule = 1 watt-secondkilo = 1,000hour = 3,600 seconds1 kilowatt-hour = 1,000 x watt x (3,600 seconds) = 3,600,000 joules
What is a commercial unit of energy?
While the SI unit for energy is the joule (equal to watt x second), commercially the kWh (kilowatt-hour) is used. Since kilo means 1000, and an hour has 3600 seconds, a kilowatt-hour is equal to 3.6 million joules.
A 60 watt light bulb runs for 5 seconds how much energy does it use?
That would be 40x60 watt-seconds, also known as Joules, so it's 2400 Joules of energy. 3.6 MegaJoules is equal to one kilowatt-hour, also known as 1 unit.
What is SI and commercial unit of energy?
The SI unit of energy is Joules The commercial unit of energy is KiloWaltHour(KWh) The relationship between SI unit and commercial unit is: 1 KWh=3.6*106J (or 3600000 J) One KiloWaltHour is: 1kWh = 1kW * 1h And the definition for kWh is: 1kWh is the electric energy consumed by an appliance of power 1 whenit is used for one hour
What does a kilowatt-hour measure?
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.
What is difference between Kilowatt power vs 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.
What measurement is energy measured in?
It depends, If you measure your own energy it would be in joules, if it is for your house you measure it with kilo-watt hour
What is the equation of converting horsepower to joule?
Horsepower is a unit of power, but joules is a unit of energy. To convert horsepower to joules, you need an additional time parameter. One horsepower is about 745.7 watts. So a horsepower-hour is 745.7 watt-hours. One watt-hour is 3600 joules. A horsepower-hour is then 745.7 times 3600 = 2684520 joules.
What unit measures electrical energy consumption?
In physics, the total amount of energy is measured in joules. The rate of energy use - joules/second - is the power, the unit is also known as watt. Electricity companies tend to use another measure for energy use: the kilowatt-hour (kWh), which of course is equal to 3.6 million joules.
Write a relation between commercial unit of electricity and the SI unit of energy?
1 kWh = 3,600,000 joules (or watt-seconds).
What is cost of btu?
This depends on the cost per kilowatt hour in your area.
How many joules are equivalent to one kilowatt per hour?
The energy 1 kilowatt-hour (kWh) is 3600000 joules.AnswerThere is no such thing as a 'kilowatt per hour'. You probably mean 'kilowatt hour'?
One kilowatt equals how many btu per hour?
A BTU is about 1055 joules. A kilowatt is 1000 joules/second, so it is 3,600,000 joules/hour. Dividing that by 1055 joules gives you the equivalent of about 3400 BTU/hour.
What units are used in electric utilities?
Kilowatt-hour (KWh) which is an energy unit equivalent to a power of 1000 Watts running for 1 hour = 1000x3600 Joules =3.6million Joules. 1 kWh is sometimes called in the trade " 1 unit".
The amount of energy used when you consume one kilo-watt in one hour?
One kilowatt-hour, or KWH.Additional AnswerYou don't 'consume power'; you consume energy. Power is a measure of the rate at which you consume energy.
How are mw and kwh related you understand how mw and kw or mwh and kwh are related but cannot find a relationship to answer your question?
Joule is a unit of energy; Joule is the same as watt-second. A watt is a unit of power, meaning, joules/second (joules per second). It is used to measure how fast energy is produced, used up, or transferred.kilowatt (1000 watts) and megawatt (1,000,000 watts) are simply multiples of the watt.Electricity bills use the unit kilowatt-hours - it refers to the energy you use if you use a power of one kilowatt, during an hour. Note that a kilowatt is a unit of power; kilowatt-hour is again a unit of energy (equivalent to 3,600,000 Joules or watt-seconds).MWh and GWh are, once again, multiples of the watt-hour (or, if you prefer, of the kilowatt-hour).
