Electronics and Communication Engineering deals with the effects and behaviour of electrons to develop systems, devices, components or equipment, integrated circuits that use electricity as the driving force. It also includes instrumentation engineering, telecommunication, semiconductor circuit design and power engineering. Electronics engineers play a major role in improving productivity in industries like oil, energy and agriculture. In steel, petroleum and chemical industries it is the electronic devices that direct, control and test production processes. Health care industry depends on electronic instruments to perform chemical tests and to check body functions
