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. |

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. |
