Question

A 500 w machin is used for 10 hours find the amount of electrical energy consimed by it in kwh

Answer 1

            500*10 KWH=5000 kwh

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!
