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.
