Electronics Vs Electrical Engineering
Electrical engineering refers to electrical machinery, problems of generation, transmission and distribution of electrical energy, electrical controls in factories, motors and their control and transformers. One of its objectives is to provide electrical power to customers.
Electronics engineering deals with semiconductor devices such as Diodes, Bipolar Junction Transistors, Metal Oxide Semiconductor Field Effect Transistors and their interconnections on a printed circuit board as well as in the form of integrated circuits. In includes Analog Electronics, Digital Electronics, Power Electronics, Microelectronics, Computer Networking, Consumer Electronics and Embedded Systems. The field is of great importance and has resulted in rapid industrial growth in this area.
Electrical engineering relates to the problems associated with large-scale electrical systems such as power transmission from power house to the load. It also deals with electrical appliances and their control. Electronics engineering deals with the study of small-scale electronic systems including computers and integrated circuits and their applications to process information.
Electrical Engineers typically posses academic degree in Electrical Engineering or Electrical and Electronics Engineering from Indian Universities. The degree spans for four years, designated as Bachelor of Engineering (B. E.) or Bachelor of Technology (B. Tech.) at undergraduate level and with specialization in the subject domain at Post graduate and Doctorate level.
The undergraduate syllabus in the Indian universities typically include major subjects of Electrical Machines, Switchgear protection, Electrical Drivers, High Voltage Engineering, Power System Analysis and Control, Power System Protection.
Electronics Engineers typically posses an academic degree in Electronics Engineering, Electronics & Communication Engineering or Electronics & Instrumentation Engineering. The degree spans for four years, designated as Bachelor of Engineering or Bachelor of Technology at undergraduate level and with specialization in the subject domain at Post graduate and Doctorate level. The undergraduate syllabus in the universities typically includes major subjects of electromagnetics, network analysis, electronic devices and circuits, signals and systems, control systems, analog and digital communications.
Electrical Engineering may include Electronics Engineering as well. Some of the universities do not distinguish between Electrical Engineering and Electronics Engineering. They have only department of Electrical Engineering in which they cover subjects belonging to both the branches.
Major professional bodies of Electrical as well as Electronics Engineers include Institute of Electrical and Electronics Engineers (IEEE), Institute of Electrical Engineers (IEE), Springerlink Journals, Science Direct Journals, Association of Computing Machinery (ACM). IEEE serves as most important and powerful organization for electronics engineers.
There are tremendous job opportunities in the domain of Electrical Engineering which include positions in government / private sectors in generation, transmission and distribution of electrical power, e.g. state/central government run electricity boards, plant engineers, electrical design engineer, field application engineer, automation engineer etc.
There exists excellent job opportunities in the domain of electronics and communication engineering as well as electronics and instrumentation engineering. The field opens up the opportunities for under graduate and post graduate students spanning the areas of signals processing, embedded systems, control systems, computer networking, industrial electronics, VLSI Designs, Digital Signal Processing, Satellite Communications, Optical Fiber Communications etc.
