Transcript of Electrical and Electronics Ebgineering _ Dr Paul K Joseph
WHAT IS ELECTRICAL ENGINEERING?
Fields of study
Power: Creation, storage, and distribution of electricity
Control: Design of dynamic systems and controllers for the systems
Electronics/Microelectronics: Design of integrated circuits, microprocessors, etc.
Signal Processing: Analysis of signals
Telecommunications: Design of transmission systems (voice, data)
Computer: Design and development of computer systems
Instrumentation:Design of sensors and data acquisition equipment
Fields of study
Transformers and alternators
Inductors are located in both transformers and alternators, allowing voltage conversion and current generation, respectively
Transformer converts from one voltage to another Alternator produces AC current
A steam turbine used to provide electric power.
