Question

Find the energy in KW H consumes in 10 hrs by four devices of power 500W each ......plzz ans some one...bestiies

Answer 1

Hey friend,

Power = 500 W =0.5 kW  

Time = 10 hour

power = energy / time  

0.5 = Energy/10  

0.5 * 10  =  Energy  

E = 5 kWh  

Now, Energy consumed by 4 machines = 4*5 = 20 units.

Hope this helped!!!!

Answer 2

Given,

➡️Power = 500W = 0.5KW

➡️Time = 10h

To Find:-

Energy

Calculations:-

We know that,

Power = energy/Time

Now substituting the given values.

0.5 = Energy /10

Energy = 0.5/10

So,

Energy = 5KW H

Now,

Energy consumed by 4 devices

=4×5

=20units.
