Electronic components

Electronic components can be classified in:

For a circuit to be properly called “electronic circuit” it must contain at least one active element.

Passive components

Fixed resistors

Capacitors

Device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other.

The property of a capacitor is the capacitance (C) that is defined as the amount of charge that can be stored at a given voltage. It is measured in Farads (F)

Active components

They are made up of semiconductor materials, whose properties allow to introduce "control" in the circuit. 

Diodes

Devices that allow current to flow just in one direction.

The most known are LED's: Light Emitting Diode

Transistors 

It is a semiconductor device used to amplify or switch electrical signals and power. It is composed of semiconductor material, usually with at least three terminals for connection to an electronic circuit. A voltage or current applied to one  of the transistor's terminals (Base) controls the current through another pair of terminals (Collector and Emitter)

There are two main types of transistors depending on the sense of the controlled current: NPN and PNP
