Question

A fan of 60 W runs for 75 hours in a month. How much electrical energy is consumed?​

Answer 1

4.5kilowatt hours

that is: power,P=60 watts =60/ 1000 0.06kilowatt and time. t= 75hrs now putting in the equation we get E= (0.06)(75) =4.5kilowatt hours thus the electrical energy consumed is 4.5 kilowatt hours.
