Electrical engineering, one of the core branches of the engineering discipline, deals with the study, design, and application of equipment, devices, and systems that use electricity, electronics, and electromagnetism. Electrical engineers work with all kinds of electronic devices, from the smallest pocket devices to large supercomputers. They develop and supervise the manufacture of electrical equipment and electrical systems for the automobile and aviation industries including electric motors, machinery controls, radar and navigation systems, communication systems, power generation and transmission devices used by electric utilities, as well as lighting and wiring in buildings.
Reason Number 1: Aptitude Required
Electrical engineering is best-suited to those passionate about technology, mathematics, and science. Aspirants should be detail-oriented, systematic, and highly computer-literate. Good communication skills, an analytical mindset, and logical problem-solving abilities are also essential in this field. Applied creativity with minute attention to detail is also among the vital talents required for electrical engineering.
Reason Number 2: Current Trends
Being one of the core engineering fields, electrical engineering has a lot going for itself. Some of the trends that are popular in this stream are:
- Smart Grid: Smart grid is an electricity supply network that uses digital communications technology to facilitate efficient and reliable end-to-end intelligent two-way delivery systems from source to sink, through the integration of renewable energy sources, smart transmission, and distribution. Its key benefits are greater reliability and reduced operating costs.
- Wireless Power Transfer (WPT): Wireless power transfer can be defined as the transmission of electrical energy from a power source to an electrical load without wires as a physical link. By eliminating mechanical connectors and wired contacts, WPT reduces costs, allows for charging of multiple devices, and prevents corrosion and sparking.
- Electric vehicles: An electric vehicle is an alternative-fuel automobile that is propelled by one or more electric motors, using energy stored in rechargeable batteries. Hybrid and plug-in electric vehicles can help increase energy security, improve fuel economy, lower fuel costs, and reduce emissions.
Reason Number 3: Higher Education
Even after doing B.Tech or BE in electrical engineering, the students have a lot of scope for higher studies. They can choose to pursue the following courses after their B.Tech/BE:
ME (Master of Engineering)/MTech (Master of Technology) in
- electrical devices and power system engineering
- electrical drives and control
- electrical energy systems
- electronics and telecommunications engineering
- power and energy system engineering
- electrical drives and embedded control
- industrial drive and control
- power apparatus and control
- applied electronics
- electronic design and technology
• MPhil (Master of Philosophy)
• PhD (Doctor of Philosophy)
Reason Number 4: Future Prospects
After completing their B.Tech/BE in electrical engineering, students can also opt for any of the following jobs:
- Electrical Design Engineer: Electrical design engineers develop new electrical systems for various applications by using systematic design methods. They use layout diagrams, terminal plans, and electrical schematics for testing, developing and debugging designs in the lab.
- Electrical engineering technologist: An electrical engineering technologist conducts or supervises the installation, commission, and operation of electrical equipment (other than aircraft electronics or instruments). He or she is also responsible for diagnosing, testing and analysing the performance of electrical assemblies and systems.
- Marine Electrical Engineer: A marine electrical engineer advises scientific crews on the most suitable use of electrical power. He or she develops technical manuals, troubleshooting procedures, drawing updates, operating procedures, maintainability improvements and test reports; validates/verifies various electronic and electrical systems; helps determine electrical requirements; and supervises the adapting and connecting of scientific equipment to shipboard power.
- Electrical and Electronics Drafter: Electrical and electronic drafters are responsible for drawing wiring diagrams, circuit-board assembly diagrams, schematics, and layout drawings used in the manufacture, installation, and repair of electronic devices and components. They also examine electronic schematics and supporting documents to develop, compute, and verify specifications for drafting data, such as the configuration of parts, dimensions, and tolerances.
- Electrical Power-Line Installers and Repairers: It is the duty of an electrical power line installer to adhere to safety practices and procedures, such as checking equipment regularly and erecting barriers around work areas. He or she should also be able to maintain and repair electrical distribution and transmission systems, including conduits, transformers, circuit breakers, and switches.
Reason Number 5: Top Leaders in the Field
Some of the top leaders who have made a mark in the field of electrical engineering are:
Vasudev Kalkunte Aatre: A former member of the Defence Research & Development Service (DRDS), Aatre is credited with developing sonar technology for the Indian Navy, as well as with designing INS Sagardhwani, India’s first marine acoustic research ship.
Debatosh Ghosh: Ghosh contributed to the areas of microstrip and dielectric resonator antennas (DRAs). He is a pioneer in introducing defected ground structure (DGS) integration technique for antenna applications which is now being explored and used by industries, especially for new-generation airborne radar.
Soumitro Banerjee: Banerjee’s research has focused on nonlinear dynamics and bifurcation theory and his experiments and analyses widened the understanding of border collision bifurcations. He has also worked extensively on nonlinear phenomena in power electronics.
Vivek Borkar: Known for introducing analytical paradigm in stochastic optimal control processes, Vivek Borkar is currently an Institute Chair Professor at the Indian Institute of Technology Bombay in Mumbai.
S.C. Dutta Roy: Known to have done extensive researches on digital and analog signal processing, Dutta Roy’s principal areas of expertise include network synthesis, solid-state circuits, distributed networking, and signal processing.
