I am in London, Uk. How much power does a pc,laptop,tubelight,bulb,... consume per day and the cost of it ?

Answer 1

every electrical appliance has a wattage requirment. ex. a 100 watt light globe burns for 10 hours which is 1000 watt hours. electricity is sold in kilowatt hours. one kilowatt is 1000 watts. divide the watt hours by 1000 equals 1 kw. in my area a kw hour costs10 cents. thus it costsme thus my cost for burning that globe for one hour is ten cents.
