Any appliance should have a label attached giving its rating in Watts or kilowatts. This is for when it is running, appliances like fridges should also have a rating based on their average power consumption.

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.
What is the difference between Hz and watts?
'Hz' is the symbol for 'hertz', the SI unit for frequency -equivalent to a 'cycle per second'. The frequency of your supply is 50 Hz in Europe, or 60 Hz in North America.The 'watt' is the SI unit for power, which is the rate at which your electrical appliances use energy.
What is difference between kilowatt hour and kiloamp hour?
A kilowatt hour is the amount of energy consumed, over a period of one hour, at the rate of one kilowatt. It's used by your electricity utility company for measuring the energy you consume, for the purpose of billing. It's SI equivalent is measured in joules.A kiloampere hour is a unit of charge. It's SI equivalent is measured in coulombs. Batteries are often rated in ampere hours.
Why are household appliances almost never connected in series?
Because it one of the household appliances were to "go out" then all the household appliances would "go out" as well.
What appliances would have a 3amp fuse?
Depending on your voltage supply appliances of between 500 - 750 watts
What is the rate which appliances consume energy?
Any appliance should have a label attached giving its rating in Watts or kilowatts. This is for when it is running, appliances like fridges should also have a rating based on their average power consumption.
What is the benefit of star rating on electrical appliances?
because they consume less energy so it is the benefit of star rating
A couch potato might consume 6 million Joules of energy in a day What is this rate of energy consumption in watts?
Rate of energy= 69.4 watts.
How much power in watts will an led bulb consume if its energy is 6 joules?
Joules (energy) are not equivalent to Watts (power).If something converts 6 Joules every second, it is 6 Watts. If it takes ten seconds to convert 6 Joules, its power is 0.6 Watts.Multiply the Watts by the seconds to find the Joules.CommentYou do not 'consume' power. Power is simply a rate; you cannot consume a rate! You consume energy; the rate at which you consume it is power.
Which appliances are the most expensive to run?
Any appliances that have high wattage rating will consume more energy. Like for example a flat iron with 1,200 watts and another with 750 watts.
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.
If 220 volt appliances consume half the power of 110 volt appliances why aren't refrigerators being sold in the USA with 220 volts?
True, 220 volt appliances consume less energy than 110 volt ones, but in order to use them in the US, you would need to convert them to 110 voltage. This is a less efficient use of energy. Plus, 220 volt appliances are a more risky because people can get seriously injured if they get shocked from them.
What appliance or device uses a lot of energy?
To the best of my understanding, appliances that use resistance components like electric geysers, water heaters and appliances with sizeable moving parts consume quite an amount of electricity.
What transfer the most energy appliances that provide heat energy or appliances that provide other forms of energy?
appliances that provide heat energy
Where are the places in a house that typically consume more energy?
The kitchen in the home typically uses more energy than any other room. Most of the appliances are used there along with the range, oven, microwave and refrigerator.
What energy do appliances such as toasters and irons use?
All home kitchen appliances use electrical energy.
What is the relationship between appliances power rating and the amount of heat it produce?
power rating is the rate of moving energy their relationship in the amount of heat it produce it divided by time to move that much energy
