Electronics is a science that studies electrical devices that are run by regulating the flow of electrons or electrically charged particles in a system such as mobile phones, computers, electronic devices, thermocouple, semiconductors, etc.
The science of studying such tools is an offshoot of Physical Sciences, while the model and design of electronic circuits are part of Electrical Engineering, Computer Engineering, and Instrumentation.
Major changes in electronics occurred around the 1960s, when an electronic device called Transistor was discovered. So it is possible to produce a tool with a smaller size which in ancient times still use vacuum tubes that are very large and also wasteful of electricity.
After 10 years in the transistor discovery, scientists finally found an integrated circuit commonly called IC (Integrated Circuit) which is an integrated circuit containing tens to millions of transistors in it.
That can make electronic devices smaller form is also more and more functions such as mobile phones that you have today, It’s all the result of the Silicon revolution as the basis of the material of making a Transistor and IC or CHIP.
To understand about this basic electronics, there are several basic topics :
