Solution
Kilowatt- hour (kWh) is the commercial unit of measurement of energy. It is also known as unit.
So, total units consumed are 650.
We can establish a relation between kilowatt-hour (kWh) and Joule (J) as –
1 kilowatt-hour = 3.6 ×106 J
So,
650 kilowatt-hour
= 650 × 3.6 × 106 J
= `2.34 xx 10^9` J
