Electronics involves investigation into the behavior, movement, and control of electrons (or electricity). In particular, electronics encompasses the design and creation of circuits using specific componentry such as transistors and microchips, and manipulation of electron flow using vacuums, gasses and semiconductors. The movement of electrons is achieved by devices that resist, switch, guide, and store electrons.
Electronics is prevalent in all walks of society in varying levels of sophistication. Central to the ideation and creation of electronics products or services are electronic engineers.
The origins of the electronic engineering profession can be traced to the telegraph industry in the late 1800s and telephone and radio technologies from around one hundred years ago. A captivation with radio and communication stimulated demand for services and later a strong interest in transmission involvement. The Second World War and the associated explosion of electrical equipment for services such as radar, sonar, communication and warfare further influenced the growth of the electronic engineering profession.
A diverse range of electric engineering subfields exists today including consumer electronics, telecommunications, radio engineering, control systems, signal processing power electronics, computer engineering, robotics and embedded systems
Electronic engineers are typically highly trained and intelligent. A Bachelor's level degree in Engineering, Science, Applied Sciences or Technology is common, with a minimum 3-4 years study conventional. The study typically extends entrants knowledge in the fields of physics, chemistry, mathematics and other topics specific to electronics. Some engineers will embark on further study towards a Masters of Engineering or Engineering Doctorate.
