Question

A certain household consumes 650 units of electricity in a month. How much is this electricity in joules?

Answer 1

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
