What is Electronics?

Electronics is a branch of science which deals with the study of the flow of electrical charge (electrons and holes) in different materials and components such as resistors, capacitors, inductor, diodes, transistors and other semiconductor devices which operate at relatively low voltages.

Electronics started in early 1900 when Dr. Lee De Forest, an American scientist, invented the Audion, a vacuum tube which amplifies a weak electrical signal.
