In one sentence the answer might be Electrical Engineering is studies about Generation Transmission and Distribution and Utilization of Electrical Energy.
Thermal, Hydel, Solar, Wind are different power plants used to generate the electrical power. A large and very complicated network is used to transmit this power to the consumers. The things like electric motors generators transformers many electrical equipment are part of this whole electrical system.
Electrical engineering is divided into few courses, study of which gives the understanding of how the above system works. The four main pillers on which the electrical engineering is standing are
- Power System
- Electrical Machine
- Power Electronic
- Control System
Power System deals with flow of Electrical Power though transmission lines. Studying Electrical Machine course you will get tk know about working and usage of Generators and Motors. Generators are used to generate electricity by transforming mechanical energy to Electrical energy whereas Motors ulilizes the Electrical energy to drive anything mechanically. Powee Electronics is about semiconductor devices used to control and condition the Electrical power for efficient usage of electricity. Control system is studied to know how to control the systems for stable operation of the whole system, predict the behaviour of the system mathematically.
Apart from this electrcal engineering courses are
- Circuit Theory
- Measurement
- Microprocessor
- Field Theory etc etc.
Unlike earlier days trend is now multidisciplinary. An electrical engineer is need strong knowledge of computer programming because of the penetration of computer technology in every engineering aspect. Apart from the core papers Electrical engineering students have to go though courses like C programming, JAVA programming, Digital Signal Processing, Artificial Intelligence etc etc.
That is why right after the completion of Graduate Degree an Electrical Engineering student will have huge scope in Core Industries as well as in Software Sector.
