Question

calculate the electric energy consumed by 5 fans each of 50 w operated for 5 hr for a month

Answer 1

Answer:

50 watt/hour

solution:-

Power of one fan= 50 w

hence,

power of 5 fans = 5×50= 250 w

Electric energy = power/time

Electric energy = 250/5 watt per hour

Electric energy= 50 watt per hour.
