Key Stage 2

Meaning

A component is a part of an electrical circuit.

About Components

Components in a circuit are used to do different jobs.
The components you should know are:

Examples

Electrical Cell Wires Filament Bulb
 
 
 
 
 
 
A cell makes the electricity flow in a circuit. Wires are the path for electricity to flow. A filament bulb lights up when electricity flows through it.
Switch Buzzer Motor
 
 
 
 
 
 
A switch can complete or break a circuit to turn it on and off. A buzzer makes a sound when electricity flows through it. A motor spins when electricity flows through it.

Key Stage 3

Meaning

A component is a part of an electrical circuit.

About Components

Components in a circuit are used to do different jobs.
The components you should know are:

Examples

Electrical Cell Wires Filament Bulb
 
 
 
 
 
 
A cell makes the electricity flow in a circuit. Wires are the path for electricity to flow. A filament bulb lights up when electricity flows through it.
Switch Buzzer Motor
 
 
 
 
 
 
A switch can complete or break a circuit to turn it on and off. A buzzer makes a sound when electricity flows through it. A motor spins when electricity flows through it.
Resistor Voltmeter Ammeter
 
 
 
 
 
 
A resistor reduces the flow of current through a circuit. A Voltmeter is used to measure the Potential Difference between two points on a circuit. An Ammeter is used to measure the Current passing through part of a circuit.

Key Stage 4

Meaning

A component is a part of an electrical circuit.

About Components

Components in a circuit are used to do different jobs.
The components you should know are:

Examples

Electrical Cell Battery Variable Power Supply
 
 
 
A cell makes the electricity flow in a circuit. A battery is several cells connected together. A variable power supply is a source of electricity with a potential difference which can be changed.
Alternating Current Supply Wires Filament Bulb
 
 
 
An alternating current supply is a source of electricity with an alternating current. Wires are the path for electricity to flow. A filament bulb lights up when electricity flows through it.
Switch Buzzer Motor
 
 
 
A switch can complete or break a circuit to turn it on and off. A buzzer makes a sound when electricity flows through it. A motor spins when electricity flows through it.
Resistor Voltmeter Ammeter
 
 
 
A resistor reduces the flow of current through a circuit. A Voltmeter is used to measure the Potential Difference between two points on a circuit. An Ammeter is used to measure the Current passing through part of a circuit.
Variable Resistor Light Dependent Resistor Thermistor
 
 
 
A variable resistor can change resistance controlling the current flowing through a circuit. A light dependent resistor (LDR) changes resistance depending on light intensity, the lower the intensity the greater the resistance. A thermistor changes resistance depending on the temperature.
Diode Light Emitting Diode Fuse
 
 
 
A diode only allows current through in one direction. A light emitting diode (LED) only allows current through in one direction and produces light when a current passes through it. A fuse is a thin piece of wire that will melt if too much current passes through it.
