Question:

What is the commercial unit of electrical energy ? Represent it in terms of joule.

Solution:

kilowatt hour (kWh) is the commercial unit of electrical energy.

$1 \mathrm{kWh}=1000 \mathrm{Watt} \times 3600 \mathrm{~s}$

$=3.6 \times 10^{6} \frac{\mathrm{J}}{\mathrm{s}} \times \mathrm{s}$

$=3.6 \times 10^{6} \mathrm{~J}(\because 1 \mathrm{Watt}=1 \mathrm{~J} / \mathrm{s})$
