Round and Round

Let's move on to electrical circuits, in which electrons move around and around in a circle, doing all kinds of useful things in the process. This is the kinds of electricity involved when you use a device that is powered by batteries or by plugging it into the wall. Look around you. How many such devices do you see?

The important thing about electrical circuits is that the circle cannot be broken. There must be an intact path for the electrons to flow through. Here's a fun game you can play that will give you a basic understanding of the way that electrical circuits work. You should note that this game was developed in Great Britain, and it uses some different words. For example, it calls a flashlight a "torch", and the power from electrical wall plugs is called the "mains". Other than that, you should be able to understand the game.
