Power of each fan=120w=0.12kw

No of fans=5

therefore,Total power= (5×0.12)kw=0.6kw

time=4h

Therefore,energy=power×time

= (0.6×4)kwh

=2.4kwh

Answer:

Explanation:

Power of each fan=120 W

No. of fans=5

Total power=120 X 5 watt

=600 W

=600/1000 kW

=0.6 kW

t =4 hour

P=E/t

E=P X t

=0.6 kW X 4 hour

=2.4 kWh
