Question

Find the energy in kwh consumed in 10 hours by a machine of power 500 w.

Answer 1

since energy is equal to power into time

so energy =500/1000*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!
