Question

find the energy in kwh consumed in 10 hours by 4 devices of power 500 Watt each

Answer 1

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 = 5kWh

Therefore, power consumed by 4 such devices = 4 × 5 kWh =  20 kWh

Hope it Helped!!!

Answer 2

Hii There!!!✍️✍️

Here is your Answer

=> Given ,
Power consumed by each devices = 500 W => 0.5KW { 1 kw = 1000 W }
As We know that ,
[ Watt is the SI Unit of Power ]

=> Power consumed by each one in = 10 hours

Now ,
We know that ,

Power = Work / Time

OR

Power = €nergy / Time

0.5 = Energy / 10

Energy = 0.5 × 10

= 5 KWh

Now , Power consumed by 4 devices = 4 × 5 KWJ = 20 KWh.....

==================

☺️Hope this will help uh☺️
