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