The document outlines various fields of electrical engineering, including power, control, electronics, signal processing, telecommunications, computer, and instrumentation engineering. It discusses components like transformers and alternators, as well as applications in communications technology such as broadcasting and internet services. Additionally, it touches on optical transport networks and client-access networks.

1. WHAT IS ELECTRICAL ENGINEERING?

2. 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

3. Telecommunications:
Design of transmission systems (voice, data)
Computer:

Fields of study

5. 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

7. A steam turbine used to provide electric
power.
