How do you convert 1997436.144 Kilojoule to KiloWAtt?
You can't convert from Joules to Watts because Joules is a measure of total energy, and Watts measure energy per second.
What metal is the heating element in a kettle?
It's basically the same as the glow wires in a toaster, or the filament in an incandescent light bulb. When a current is passed through the element, the resistance makes the element heat up.Another AnswerWhen an electric current passes through the heating element, it does work on the heating element, water, and the kettle itself. This causes the internal energy of the element, water, and kettle to rise, and this is accompanied by an increase in temperature. When the temperature exceeds that of the surroundings, some energy is lost to the surroundings through heat transfer. The equation that describes this is:W - Q = [m c (T2 - T1)]water +[m c (T2 - T1)]kettleWhere:W = work done (joules)Q = heat transfer (joules)m = mass (kilograms)c = specific heat capacity (joules per kilogram kelvin)T2 = final temperature (kelvin)T1 = initial temperature (kelvin)
How many Therms per kWh?
A therm is an energy unit (equal to 100000 BTU) while kilowatts are power (energy/time). 1 watt = 1 Joule/second, and 1 kilowatt = 1000 Joules/second. The kilowatt hour is an energy unit (power X time = energy). 1 therm = 29.31 kWh
If you use 10 joules of work to push 1 coulomb of charge into an electric field its voltage with respect to its starting position is?
10 voltage
Is 3.25kcal the same amount of energy as 3.25jouls?
No, to convert from cal. to joules 1 cal. = 4.18400 joules , then 1KCal = (4.18400 *10^-3) joules so 3.25 kcal doesn't equal 3.25 Joules
How many kilowatt hours in one tetra joule?
1 kilowatt hour = 3,600,000 Joules 1 Tetrajoule = 1,000,000 Joules 1 kilowatt hour = 3.6 Tetrajoules
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.
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.
An electric heating element is connected to a 110 V circuit and a current of 3.2 A is flowing through the element How much energy is used up during a period of 5 hours by the element?
If an electric heating element is connected to a 110 volt circuit and a current of 3.2 amp is flowing through the element, 63.36 million joules of energy is used up during a period of 5 hours. This is also 1.76 kilowatt-hours.110V times 3.2A equals 352 watts (joules per second).352 watts times 3600 seconds per hour times 5 hours equals 63,360,000 joules.
Conert 365 kilo watt hours to joules?
365 kilowatt-hours is 1,314,000,000 joules.
What are bigger units of works?
Well since Joule is the standard unit a Megajoule (1 million joules) or a kilojoule (1000 joules) can be used. Also a kilowatt-hour (3.6 million joules) is used by electric companies to keep track of the energy people use.
What do you call one thousand watts?
The kilowatt (kW) is one thousand watts.
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".
How many watts in 1 kilowatt?
Killo = 1000. There are 1000 watts in 1 kw.
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'?
How many joules are there in a kilowatt-hour?
These do not have the same units. 1 kilowatt hour per meter cubed is in kg m-1 s-2 1 kilojoule per kg is in m2 s-2
How do you convert joule to kilowatt-hour?
Joules x 0.000000278 = kW/h
