Question

find the energy in KW h consumed in 10 hours by four devices of power 500W each.​

Answer 1

Answer:

power in kw = 500/1000 = 0.5Kw

power of four devices = 4 x 0.5 = 2Kw

energy consumed by them = 2 x 10 = 20kwh

Answer 2

Answer: 5kWh  

Explanation:    

Energy consumed = Power x Time = 500 W x 10 h = 5000Wh = 5kWh.

1 device = 5kWh  

4 devices = 20kWh

 

Hence, the amount of energy in kWh is consumed in 10h by 4 devices of power 500W​ is 20kWh.
