Question

5 exhaust fan of 140 what each are used for 4 hours calculate the electrical energy consumed in kilowatt hour

Answer 1

Answer:

2.8 kilowatt hour

Explanation:

Energy consumed = Power * Time

                               = 140 * 4

                               = 560 watt hour

                               = 560/1000 kilowatt hour

                               = 0.56 kilowatt hour

As there are 5 exhaust fans, the total energy consumed is 2.8 kilowatt hour
