Basic Theory of Science: So let us have the overview of some basic theories of science which you may already know, or some of you will study f…

#The word "Electronics" is a combination of two words i.e. "Electron" and "Mechanics". Hence Electronics can be defined as a branch of science which deals with mechanics of flow of electrons. The base of this subject is to study: why, how, how much, in which direction the electrons are flowing and that is nothing but mechanics.

#Italian physicist Alessandro Volta discovered that particular chemical reactions could produce electricity, and in 1800 he constructed the voltaic pile (an early electric battery) that produced a steady electric current, and so he was the first person to create a steady flow of electrical charge. But Electron which is the base of flow of electric current was discovered by J. J. Thomson in 1897. So, there was a gap of around 97 years between both discoveries.
