Description

This is a basic physics GCSE tutorial exploring in simple terms what the energy rating of electrical items refers to. Video tutorial to come.

What is energy rating?

We've learned that energy is what you use to do work. At this stage, we usually think of work as moving an object from one location to another. Work is also used to do many other things, including the running of electrical items.

Electrical items like fridges will have a energy rating sticker on them.



This tells you how efficiently a fridge can maintain a certain temperature. The better the rating, the less energy required to maintain that temperature. We can make fridges more efficient by
