Question

Find the energy in kwh consumed in 10h by a machine of power 500 W

Answer 1

5 kWh or 5 units . E=P(in kW)×T(h) , E= ½×10= 5kWh

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

Good day!
