Energy = Power * Time

500*4 = total power of four devises

Time = 10 hours

Energy = P*T

2000*10

= 20000 or 2 killowatthour

Hey there!

Given,

Power ( P) = 500 W =0.50 kW

Time (t) = 10 h

We know,

Work done = Energy consumed.

Power = work done / time

0.50 = Energy consumed / 10

Energy consumed  = 0.50 * 10 = 5 kWh

Now,

Energy consumed by four devices = 4 * 5 = 20 kWh.

Good day!
