Question

A machine of 500W works for 2hrs. Find the no of units of electricity consumed.

Answer 1

Answer:

Thus, There will be 1 Unit of Electricity Consumed.

Explanation:

Given,

        A machine of 500W works for 2hrs.

We need to find the number of units of electricity consumed.

Sol: We have,

                     Power, P = 500W

                                     = 500/1000W

                                     = 0.5W

               and Time, T = 2hrs

         We know, The Work, W = P x T

                                             W = 0.5 x 2

                                             W = 1 KWH

                                        or W = 1 Unit

          Thus, There will be 1 Unit of Electricity Consumed.
