Electrical energy consumed is given as,
E= P x t
Power (P) is given in Watt.
To convert given power in kiloWatt we have to divide the value by 1000,
Thus,
![E equals P over 1000 k W space cross times space t space h o u r
rightwards double arrow space E space equals space P space cross times space t space cross times space 10 to the power of negative 3 end exponent space k W h](https://images.topperlearning.com/topper/tinymce/cache/aeb93bde2589dc7ef02f32f214b9ed76.png)
