Explanation:

We know that kWh is a commercial unit of energy.

Also, 1 Joule = 1 watt × 1 seconds

[tex]1\ kWh=1kW \times 1\ h[/tex]

Since ,1 h = 3600 s and 1kW = 1000 W

[tex]1\ kWh=1000\ W \times 3600\ s\\\\1\ kWh = 36\times 10^5\ W-s\\\\1\ kWh=36\times 10^5\ J[/tex]

So, the relation is : [tex]1\ kWh=36\times 10^5\ J[/tex]

1 watt is defined as the power of an appliance when the energy is transferred at a rate of 1 Joule per second.
