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. |
