Electrical
engineering comprises
the study and application of electricity, electronics and electromagnetism.
Sub-disciplines
of electrical engineering and their scope:
- Computer engineering
To design and
control of computing devices with the application of electrical systems.
- Electronic engineering
To design the
circuit that use electromagnetic properties of electrical components such as
resistors, diode, capacitor, and transistor to achieve a particular
functionality.
- Power engineering
The generation,
transmission and distribution of electricity, and the design of devices such as
transformers, electric generators, electric motors, high voltage engineering
and power electronics.
- Optic engineering
The design of
instruments and systems that utilize the properties of electromagnetic
radiations.
Electrical engineers have made
remarkable contribution to our world. Electrical engineers helped invent the
computer, DSL, cellular phones, microchips and solar panels to name just a few
examples.
DVD players,
cellular phones, radio, television, computers, airplanes, space vehicles, cars,
motorcycles, home appliances, life saving medical equipments, computer games
and Martian battles fought with joysticks represent a mere sampling of now
familiar facets of life made possible with the input of electrical engineers.
