Question

Deduce the relation between kwh and joule define 1 watt​

Answer 1

Step-by-step explanation:

We know that kWh is a commercial unit of energy.

Also, 1 Joule = 1 watt × 1 seconds

`1\ kWh=1kW * 1\ h`

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

`1\ kWh=1000\ W * 3600\ s\\\\1\ kWh = 36* 10^5\ W-s\\\\1\ kWh=36* 10^5\ J`

So, the relation is :
`1\ kWh=36* 10^5\ J`

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