Knowledge organizers contain the most fundamental knowledge for the topics you are studying.

1. Electricity Year 6
Key Vocabulary Key Knowledge
circuit A path that an electrical current
Components of a Circuit and Their Symbols
can flow around.
symbol A visual picture that stands for
lamp/bulb
something else.
(indicator) wire
cell/battery A device that stores chemical
energy until it is needed. A cell is a
single unit. A battery is a collection
of cells. lamp/bulb
current The flow of electrons, measured
(lighting)
in amps.
switch
motor
amps How electric current is measured. (open)
voltage The force that makes the electric
current move through the wires. M
The greater the voltage, the more
current will flow. buzzer
resistance The difficulty that the electric
switch
current has when flowing around cell

a circuit.
electrons Very small particles that travel
around an electrical circuit.

What will make a bulb dimmer or a ctrical
current.
buzzer quieter?
• Fewer batteries or a lower voltage
give less power to the circuit.
• More buzzers or bulbs mean the power
is shared by more components.
• Lengthening the wires means the
electrons have to travel through more
resistance.
