Episode 7: Circuits

Learn all about the fascinating world of energy with Enn and Gee!

EnnUh oh, ENN and GEE are stuck on our planet – a long way from their home on Planet Zog.

They’ll need energy to get home – and lots of it!

Now where on earth are they going to find energy?

What are circuits?


Electric circuits  are collections of wires and electric components connected together in such a way that electric current can flow through them.

They’re everywhere even though you might not notice them. Every electrical appliance you can think of contains an electric circuit. 

If a circuit is broken, electricity won’t flow at all.  Sometimes breaks in the circuit can be helpful – think about switches, like light switches.

When you click them one way, it breaks the circuit and the light goes off.  Switch it the other way and… ON!

A simple circuit of a light switch will have a line travelling in a square to show the route that the electricity takes.

The bulb is shown as a circle.  The power source is shown with a plus sign where the energy comes from and a minus sign to show where it comes back.
