Electronics is a branch of physics and electrical engineering. It deals with the study and application of electronics, which is the science of controlling electrical energy electrically. It includes the design, development, manufacture and application of electronic devices, as well as computer systems for their control, monitoring and use.

The word "electronics" was coined by Tom Kilburn when he was working on radar at the UK's TRE in 1940. He coined it from the Greek word "electron", meaning amber or electron tube; so electronics literally means "the study of electrons".

Electronics is the branch of engineering that deals with electrical circuits and devices.

The word electronics has been in use since the 1920s, from the word electric + electronics, from earlier words such as electrician and electrician's mate.

Electronics are devices that display information and control other devices. They can be as simple as a calculator or as complex as an MRI machine. They are an integral part of our society and have become more prominent in recent years.

We will now take a look at various types of electronics, how they work, and what they do.
