Electronics is a science that studies weak electrical current that works by controlling the flow of electrons or electrically charged particles in a device / equipment such as thermocouples, semiconductors, computers, and other electronic equipment. The study of tools like this is a branch of physics, while the design and manufacture of electronic circuits is part of electrical engineering, computer engineering, and instrumentation.
In the 1960s there was a massive revolution against electronics. In that year discovered an electronic device called the Transisor, so that it is possible to make a device with a small size where previously the equipment was still using vacuum tubes which are large in size and consume large electricity. Only in the period of 10 years since the discovery of the transistor, was found an integrated circuit called the IC (Integrated Circuit). IC is an integrated circuit that contains tens or even millions of transistors in it. So that we can see an electronic device getting smaller but the more functions as an example of a computer that you use today with the first computer used, the size is very different. This is thanks to the silicon revolution as a basic material for making transistors and ICs or often also called CHIP.
Electronic Component consists of 2 components, namely:
1. Passive Components
Passive components are types of electronic components that work without the need for an electric current so that they cannot amplify and rectify the electrical signal and cannot convert an energy into another form.
Passive components consist of resistors, capacitors or capacitors, inductors and transformers.
2. Active Components
Active component is a type of electronic component that requires an electric current to work in an electronic circuit that can amplify and rectify an electrical signal, and can convert energy from one form to another.
Examples of active components are: Diode, Transistor, LED, IC
