What is relationship between kilowatt and joule?
What is relationship between kilowatt and joule?
E=(1000)(3600)∴E=3.6×106Joules. And here, E=1KWh. Therefore, this implies that 1KWh=3.6×106Joules. Hence, we found a relation between 1KWh and joule.
How do you convert J to kW?
It is a very simple conversion, so all you have to do is divide the Joules between time by 1000 which will convert the joules into kW. Example: An industrial fryer transforms an energy of 420000Joule every 60 seconds, how much power in kW the fryer has.
What is meant by kilowatt-hour relate 1KWh with joule?
1 KWh is defined as the 1000 J energy is used in 1 hour. Mathematically, 1 KWh=3.
What is the relation between kilowatt and kilowatt-hour?
The main difference between kWh and kW is in what they measure. To put it simply, a kilowatt is a measure of power and a kilowatt-hour is a measure of energy; power is the rate at which something uses energy, and energy is the capacity to do work.
What do you mean by 1 kilowatt?
1 kilowatt (kW) = 1,000 watts (W) 1 megawatt (MW) = 1,000 kilowatts (kW)
How is energy related to Joule?
1 Joule (J) is the MKS unit of energy, equal to the force of one Newton acting through one meter. 1 Watt is the power from a current of 1 Ampere flowing through 1 Volt. 1 kilowatt is a thousand Watts. 1 kilowatt-hour is the energy of one kilowatt power flowing for one hour.
How many kWh are in a MJ?
3.6 MJ
For example, 1 kWh [kilowatt hour] = 3.6 MJ [megaJoule].
How many kJ are in a kWh?
Kilowatt-hours to Kilojoules table
| Kilowatt-hours | Kilojoules |
|---|---|
| 1 kWh | 3600.00 kJ |
| 2 kWh | 7200.00 kJ |
| 3 kWh | 10800.00 kJ |
| 4 kWh | 14400.00 kJ |
What do you mean by 1 kilowatt hour?
A kilowatt hour (kWh) is a measure of energy. So a 1,000 watt drill needs 1,000 watts (1 kW) of power to make it work, and uses 1 kWh of energy in an hour.
How is 1 kW defined?
1 Kwh can be defined as the amount of electrical energy consumed when a 1000 watt electrical appliance is used for an hour. The unit of energy is watt. 1 Watt = 1 Joule /second. It is the amount of energy converted if work is done at the rate of 1000 watts per hour.
How many kWh is equal to one joule?
How many kWh in 1 joules? The answer is 2.7777777777778E-7. We assume you are converting between kilowatt hour and joule. You can view more details on each measurement unit: kWh or joules. The SI derived unit for energy is the joule. 1 kWh is equal to 3600000 joule.
What is the relationship between Joule and Watt?
the energy consumed per sec in watt = 1 joule per sec. the standard unit of power in the International System of Units(SI), equivalent to one joule per second and equal to the power in a circuit in which a current of one ampere flows across a potential difference of one volt. Abbreviation: W, w. 1 watt = 1 Amp current x 1 volt potential difference.
Why is 1 kWh = 3.6 MJ?
The Joule (J) is the unit of measure for energy or work. The quantity of energy to do an amount of work is the same. The Watt (W) is the unit of measure for power. 1 kWh = 1000 Wh = 1000 W x 3600 second = 3.6 MWs = 3.6 MJ
What is the relationship between Watt and kWh?
Abbreviation: W, w. 1 watt = 1 Amp current x 1 volt potential difference. If the energy is being transmitted or used at a constant rate (power) over a period of time, the total energy in kilowatt hours is equal to the power in kilowatts multiplied by the time in hours.
