A circuit will always have a battery (cell) as well as other components. Components such as bulbs, buzzers, switches and motors, need a battery in order to work.

Follow along and learn to construct a circuit.
You've got some seriously cool stuff here, Frank.
If we鈥檙e putting this Sandwich Intruder Alarm together, we鈥檙e going to need a diagram!
Sweet.
Each of these symbols are different electrical parts.
We just need to arrange them in to a circuit!
First we need power, man 鈥 this symbol here is a cell, or battery.
That one鈥檚 a motor 鈥 we don鈥檛 need that one.
But that鈥檚 a light bulb 鈥 we can use that.
Let鈥檚 finish off with the buzzer, to make some noise!
But we need the power to flooowww 鈥 let鈥檚 join it all up with wires.
Don鈥檛 forget the switch 鈥 we鈥檒l set it up so if someone treads on it, the switch will close, setting off our alarm!
Let鈥檚 check it out!

Frank! Someone鈥檚 stealing the sandwich!
Frank!?.. Frank?
Aww man鈥
When drawing circuit diagrams, rather than drawing detailed components, we use simple symbols to represent the different components.
Practise drawing the following series circuits using symbols:
