I'm doing a survey for science and I would appreciate if you knew of a web page with the average usage of watts (per hour) of: desk lamp, TV, hair dryer, curling iron, coffee kettle, washing machine, dryer, iron, fridge, microwave, computer.....etc. you get the point. It would be of much greater help if you knew the wattage of the electrical appliances in your house. Thanks for participating!!

Here are some approximate values:

desk lamp = 60 watts
TV = 100 - 150 watts
hair dryer = 1200 watts
curling iron = 50 watts (guessing on this one)
coffee kettle = 1000 watts
washing machine = 600 watts
dryer = 4500 watts (if electric heating element)
iron = 1000 watts
fridge = 150 watts
microwave = 1100 watts
desktop computer with LCD monitor = 250 watts
laptop computer = 70 watts

The values above are my estimates based on actual testing. I'm not sure how all these numbers compare to the link below.

Keep in mind that some of these applicances are not used for an hour. If you are trying to determine your home's usage, try taking some measurements on your electric meter.

Count the revolutions of the rotating disk in one minute:

RPM x 60 x Kh = watts.

Kh is a factor on the face of the meter. This value will vary depending on the type of meter. Common values in the US include 3.6, 7.2, and 12. However other values also exist.

Do the "stopwatch test" twice. Once with minimal equipment on, and then again after turning on as many applicances as you can.
