Question

Find the energy in kWh consumed in 10 hrs by four devices of power 500 W each

Answer 1

Hey mate here is ur answer

Power = 500 W = 0.5 kW
time = 10 h
power = energy / time
0.5 = E / 10
0.5 * 10 = E
E= 5 kWh

now,

energy consumed by 4 machines
=4 * 5 = 20 UNITS

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 four devices = 4 * 5 = 20 kWh.

Good day!
