Electronic component

These leads connect to other electrical components, often over wire, to create an electronic circuit with a particular function (for example an amplifier, radio receiver, or oscillator).

However, electronic engineers who perform circuit analysis use a more restrictive definition of passivity.

[5] In contrast, active components (with more than two terminals) generally lack that property.

Transistors were considered the invention of the twentieth century that changed electronic circuits forever.

A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power.

They are used for filtering power supply lines, tuning resonant circuits, and for blocking DC voltages while passing AC signals, among numerous other uses.
