Electric bulb
Power = 100 W
Time = 5 hrs
Energy = 100 W × 5 hr
= 500 W hr
Electric press
Power = 750 W
Time = 5 hrs
Energy = 750 W × 5 hr
= 3750 W hr
Television
Power = 300 W
Time = 5 hr
Energy = 300 W × 5 hr
= 1500 W hr
Daily energy
Daily energy used = 1500 W hr + 3750 W hr + 500 W hr
= 5750 W hr
Total energy
Total energy = 5750 W hr × 20
= 115000 W hr
= 115 kW hr
The energy is 115 kW hr
Hope it helps ;-)
Happy new year
