Electrical Energy and Power
Electric energy is the most important form of energy and is widely used in almost all the electrical devices around us. These devices have a rating written on them. That rating is expressed in Watts and intuitively explains the amount of electricity the device will consume. Bigger devices like AC, refrigerators, etc consume more electricity and thus come with a higher rating.
This rating explains the energy and power consumed by the device. It is very important to get an idea about the ratings and their meaning. Let’s learn about Electrical Energy and Electric Power in detail in this article.
