Basic Electronics Definition | What is Electronics

Electronics is science of controlled activities or movement of free electrons present in Atom of a matter.
The first electronic component every made in 1906 was triod or triode.

Triode - A triode is an electronic amplification device having three active electrodes.

Electronics is used in factories, at home, in medical field, defense etc.

Electronic Components:

All electronic components are divided into two categories:

  • Active Devices
  • Passive Devices

Active devices or components are those devices or components that get activated after electricity is supplied to them. Once these components get activated, they start performing their function / generate energy.

Example of Active Device: IC (Integrated Circuit)

IC - An IC or Integrated Circuit is an Active Electronic Device

Passive devices or components are those devices or components that do not generate any energy. These devices work as subsidiary (associate) devices. These devices are available in both Thru-Hole and SMD (Surface Mount Device) Form.

Example of Passive Devices: Resistor, Capacitor

Capacitor - A Capacitor is a Passive Electronic Device

Electronics:

In electronics, the flow of electrical charge from one point to another is defined. This flow of electric charge is called current electricity or simply electricity.

Flow of electrical charge cannot be seen but can only be felt in the form of light, energy or magnetic. Flow of electricity in a metal wire means “Flow of Electron”.
