How is a kWh is related to joule?
One kilowatt-hour is equivalent to the energy of 1,000 joules used for 3,600 seconds or 3.6 million Joules. In equation form: 1 kWh = 3.6 million J.
What is the magnitude of 1 kWh and joule?
The magnitude of 1 kWh is 3.6 × 10⁶ Joules.
What is the relation between SI unit of energy and kWh?
There is a relationship between the SI unit of energy and the commercial unit of energy. 1 kWh = 1kW × 1h = 1000W × 1h = 1000(J/s) × 3600 s = 3.6 ×106J.
How many ERG are there in 1KWh?
1 kilowatt hours is equal to 3.6 into 10 ki power 13 ergs.
What do you mean by 1 kWh?
Kilowatt hours (kWh) A kilowatt hour (kWh) is a unit of measurement of energy. A kilowatt hour therefore refers to the consumption of your device. 1 kilowatt hour (kWh) is the energy consumed by a 1,000-watt or 1-kilowatt electrical appliance operating for 1 hour.
How is the unit of energy related to 1 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-hour is the energy of one kilowatt power flowing for one hour. (E = P t).
Why do we use kWh instead of joules?
While the joule is the SI base unit for energy, when speaking in real-world terms, we often use the kilowatt-hour (kWh) instead. This is due to the fact that a joule is an extremely small amount of energy. To put how small a joule is into perspective, a liter of gasoline has 31,536,000 joules of energy in it.
How is kWh different from kW?
A kilowatt-hour measures the energy an appliance uses in kilowatts per hour. The difference between kWh and kW, and what you see on your bill, is that kW reflects the rate of electricity you use, and kWh indicates the amount of electricity you use.
How is kWh different from kW find the relation between commercial and SI unit of energy?
Answer: Kilowatt – hour is the commercial unit of electrical energy. SI unit of energy is joule(J) and commercial unit of energy is kWh(kilowatt-hour). Therefore, 1 kWh = 3.6 x 10^6 J.
What is the conversion factor between kilowatt hour and ERG?
Therefore 1 Kilowatt hour = 3 . 6 × 10 13 erg .
What can 1 kWh do?
Electricity usage is calculated in kilowatt-hours. A kilowatt-hour is 1,000 watts used for one hour. As an example, a 100-watt light bulb operating for ten hours would use one kilowatt-hour. Below are some examples of electrical appliances found in most homes.
How many kWh can you relate to Joule?
Relate 1 KWh (kilowatt hour) with joule. Relate 1 KWh (kilowatt hour) with joule. Please log in or register to answer this question.
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
How much energy is in a kilowatt hour?
One kilowatt-hour is equal to 3600000 joules: So the energy in joules E (J) is equal to 3600000 times the energy in kilowatt-hour E (kWh):
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.
