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 is power output?
The term power consumption is defined as the amount of electrical energy used over time in an appliance. Power consumption is measured using kilo watts.Another AnswerPower is simply a rate; the rate of energy transfer. So power cannot be 'consumed'; it's energy that's being consumed. So, when we say 'power consumption', what we mean is 'the rate of energy consumption'. As power is a rate, it is measured in joules per second which, in SI, is given a special name: the watt.
What could joules be used to measure with?
Joules are used to measure energy. Also the related concept of work, which can be thought of as the transfer of energy.
What is the rate at which work is done or energy is used is referred to?
Power.
Is electric power the same as electrical energy?
No.First of all, there is no such thing as 'electrical power', although the term is used in everyday speech. Power is simply a rate, the rate at which one form of energy is converted into another, or the rate of heat transfer. As energy is measured in joules, power is measured in joules per second which, in SI, is given a special name, the watt.Energy, on the other hand, occurs in many forms, including electrical. All forms of energy, including electrical, is measured in joules.It is energy, not power. that you pay for, when your electricity utility charges you for 'using electricity'. As the joule is a very small unit, utilities traditionally use a special unit called a kilowatt hour (kW.h) to measure that energy although there is no reason why they shouldn't use a kilojoule or megajoule instead.

60-watt light bulb in jouls?
A Watt is a Joule per second. Joules measure energy and Watts measure power, which is the rate of energy used. Therefore, if you use a 60 Watt light bulb for 10 seconds, you consume 600 Joules.
How much power is used when 600J of work are done in 10s?
60 W
What is the difference between a radio waves power and its energy?
Power, in all situations is the rate of change of energy. If the power is constant, it can be found using the formula, "Power = Energy Used / Time taken". So, the power of a radio wave (in watts) is equal to the amount of energy it transmits (in joules) per second.In symbols:P = E/t
How do you convert 30146.4 kilojoules of heat to watts or some comparable energy?
"Joules" is an absolute amount of energy. "Watts" is a rate at which energy is used or moved.1 watt means 1 joule per second.1 joule is the amount of energy that moves in 1 second, if the rate (power) is 1 watt.30,146.4 kilojoules = 30,146,400 joules.If the 'power' (rate of using energy) is 100 watts ... as in a medium incandescent bulb ...then 30,146,400 joules of energy are used in 83.74 hours.If the power is 1,000 watts ... 1 'kilowatt', as in a small toaster ... then 30,146,400 joulesof energy are used in 8.374 hours. Here, you can see the unit of energy that you've seenbefore, on your electric bill ... the "kilowatt-hour". 30,146.4 kilojoules = 8.374 kilowatt-hours.1 kilowatt-hour = 3,600 kilojoules = 3,600,000 joules
What is the energy used every second known as?
Energy / time is known as power. In SI units, time is measured in seconds, energy in joules; the unit for joules / second has the special name watts.
Is power and energy the same?
No.First of all, there is no such thing as 'electrical power', although the term is used in everyday speech. Power is simply a rate, the rate at which one form of energy is converted into another, or the rate of heat transfer.

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.
What is the metric unit for measuring energy?
Joules are the metric units used to measure energy. When you are working with any form of energy you state them in joules.
What is the amount of electrical energy used in a certain amount of time?
This is a measure of power. Power is the rate of use or production of energy. Usually it is defined as the amount of energy per second. Thus if energy is measured in Joules, then a rate of 1 Joule per second is a power of 1 watt. If you are thinking of thermal energy, this will be in calories or BTU. There is no specific unit for calories/sec or BTU/sec, but they can be related to watts. 1 calorie/sec = 4.2 watts, 1 BTU/sec = 1.055 Kw
What is the watts equivalent of 231000 joules?
231,000 joules is an amount of energy, while watts are a measure of how fast energy is used or converted. 231,000 joules could be used by 1 watt running for 231,000 seconds, or 231 watts running for 1000 seconds, etc. Energy = power x time, so 1000 watts for 231 seconds is an amount of energy equal to 231,000 joules.
