Answer:
Here you go!
Step-by-step explanation:
===========================================
Power consumed by each device = 500W = 0.5 kW
Energy consumed by each one in 10 hours -
Power = Energy / Time
0.5 = Energy / 10
Energy = 10 × 0.5
Energy = 5 kWh
Therefore, power consumed by 4 such devices = 4 × 5 kWh
= 20 kWh
= 20 units
