Power of one fan = 120 watts
Power of 5 fans = 120 × 5 watts
= 600 watts
Power ( in kilowatt hour ) = 600 / 1000
= 0.6 kilowatt hour
Time = 4 hours
Electrical energy = power × time
= 0.6 × 4
= 2.4 kilowatt hour
So the electrical energy consumed is 2.4 kilowatt hour
Power of 5 fans = 120 × 5 watts
= 600 watts
Power ( in kilowatt hour ) = 600 / 1000
= 0.6 kilowatt hour
Time = 4 hours
Electrical energy = power × time
= 0.6 × 4
= 2.4 kilowatt hour
So the electrical energy consumed is 2.4 kilowatt hour
