GRADE 6
 Electricity can flow through the components in
a complete electric circuit.
Incomplete circuit
So the electric current cant flow
Complete circuit
So the electric current flow and
Lit the bulb
Electric symbolsElectric symbols
 We use these symbols to draw diagrams of circuits:
Produce
Sound

Movement
Drawing circuit symbolsDrawing circuit symbols
SwitchesSwitches
 When a switch is open (off),
there is a gap in the circuit.
Electricity cannot travel around
the circuit.
 When a switch is closed (on), it
makes the circuit complete.
Electricity can travel around the
circuit.
Changing number ofChanging number of
batteries/cellsbatteries/cells
Adding more batteries to a simple
circuit will increase the electrical energy,
which will make a bulb brighter.
Changing number of bulbsChanging number of bulbs
Adding more bulbs to a simple circuit
will make the bulbs dimmer.
Changing length of wiresChanging length of wires
 Lengthening the wires in a simple circuit will
make the bulb dimmer.
 Longer the wire the more the resistance so less
electric current can flow and the bulb dimmer
Changing thickness of wiresChanging thickness of wires
Thicker the wire in a simple circuit will
make the bulb brighter.
Thicker the wire less the resistance
so more electric current can flow
Electrical ConductorElectrical Conductor
All metal can conduct electricity but not all are
good electrical conductor
One of the best conductor is copper thats why
it commonly used for making wire
Copper
Plastic or rubber to
insulate the electric
current
Electrical insulatorElectrical insulator
Most of non metal cant conduct
electricity
One of non metal that can conduct
electricity is graphite (pencil lead)
or carbon
If there is no electric insulator you will get electric shockIf there is no electric insulator you will get electric shock
when you touch itwhen you touch it
