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 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 flows through it. | A fuse is a thin piece of wire that will melt if too much current passes through it. |
