What is Electronics?
The word electronics is derived from electron mechanics, which means to study the behavior of an electron under different conditions of .
The device which controls the flow of electrons is called electronic device. These devices are the main building blocks of electronic circuits.
The motion of electrons through a conductor gives us electric current. This electric current can be produced with the help of batteries and generators.
Electronics have various branches include, digital electronics, analog electronics, microelectronics, nanoelectronics, optoelectronics, integrated circuit and semiconductor device.
History of Electronics:
Diode vacuum tube was the first electronic component invented by J.A. Fleming. Later, Lee De Forest developed the triode, a three element vacuum tube capable of voltage amplification.
In 1947, Bell laboratories developed the first transistor based on the research of Shockley, Bardeen and Brattain.
In 1959, Jack Kilby of Texas Instruments developed the first integrated circuit.
