in electronics, there is a term of Watt Hours used in power bills and things. watts itself is a unit derived by 1 joule per second. in order to get watt hours (which is just 1 joule per hour) you multiply your watts (joule/second) by 360 (60 seconds in a minute multiplied by 60 minutes in an hour). that will then give you units of joules/hour
What else can I help you with?
A college student produces about 100 kilocalories of heat per hour on the average what is the rate of energy production in watts?
To convert kilocalories per hour to watts, divide by 860: 100 kilocalories per hour / 860 = 0.1163 watts. So, the college student's rate of energy production is approximately 0.1163 watts.
How many watts are in a one hundred watt lamp?
None, the watts come form the electricity supply and the lamp uses them at a rate of 100 an hour when it is turned on.
How many watts does a microwave consume in an hour?
Watts are units for measuring the rate of energy consumption. So it is meaningless to speak of how many watts something consumes in a length of time. (It would be like asking how many miles per hour a car drives in an hour.)Energy consumption may be measured in kilowatt-hours. A typical microwave consumes 1500 watts, which would be 1.5 kilowatt-hours in one hour.
What is the difference between Watts and Kilowatt hours?
Watts is smaller than kilowatts. watts is unit of power and kilowatts hour is unit of energy. Electrical devices are specified in watts where as electrical bill is for kilowatt hr use.
How much is a Meter cubed per hour in W?
Meter3/hour would be a flow rate, or rate of change of volume with time.I can't think of anything abbreviated 'W' that would correspond to that unit.Certainly not 'Watts'.
How many kliowatt hours does a 120 watt fixture use in 1 hour?
One kilowatt hour (kWH) is the amount of power used at the rate of 1000 watts for one hour. Therefore a device of 120 watts running for one hour would consume 120 / 1000 x 1 = 0.12 kWH
A kilowatt-hour is equal to how many watts of electricity used for one hour?
1,000 watts
What is power expressed in?
Power is typically expressed in watts, which represent the rate at which work is done or energy is transferred. It can also be expressed in other units such as horsepower, kilowatts, or BTUs per hour depending on the context.
How long is a watt hour?
A watt hour is a unit of energy, not time -so you cannot ask how 'long' it is. The time taken to consume a watt hour of energy depends upon the rate (i.e. the power) at which it is consumed, expressed in watts. A watt hour is defined as the amount of energy consumed, over a period of one hour, at the rate of one watt.
How many watts are used in a solar cell per hour?
100 watts
How many watts does a fan use per hour?
3/4 of watts
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.
