power of 1 device = 500w
power of 3 devices= 500×3
= 1500w => 1.5kw
so, energy = 1.5 * 10
=> 15 kWh

hope it helps u

Answer 2

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 3 devices = 3 * 5 = 15 kWh.

Good day!
