An electrical component is a basic, discrete device that is often connected with others, to fulfil the requirements of a circuit.
In an electrical system, such as that which forms the electrical installation of a building, electrical components comprise items provided in a mains circuit such as switching devices, like switches and isolators, protection devices such as circuit breakers and fuses, and wiring connections.
- Active components – these would comprise transistors, integrated circuits (ICs), diodes and thermionic valves.
- Passive components – these would comprise capacitors, resistors and inductors.
