Electrical & Electronics Engineering
Imagine your life without electricity and consumer
durable like television, refrigerator, microwave, etc. - seems mundane and hard
to survive. Isn’t it? Electricity and electronic appliances became one among
our basic needs in day-to-day life. With our increasing dependency on
electrical and electronic products, the scope of electrical and electronics
engineering has also grown in giant strides as compared to previous decades. If
we mention job quotient within the different sectors of electrical and
electronics engineering, it's ever-increasing to satisfy the variegated needs
of the consumers in India also as abroad. Be it transport, banking, other
private and public sectors and even educational premises, electrical and
electronics engineering features a vital role to play in any environment.
Let’s read further what electrical and electronics engineering
(EEE) is all about.
What
is Electrical Engineering (EE)?
Electrical Engineering is that the field of
engineering that generally deals with study and application of electricity,
electronics and electromagnetism.
Electrical engineering deals with high voltage
especially AC above the range of 110 or 220v. Moreover electrical components
and devices use alternating current/voltage and have a tendency to be larger in
size and need 230v and 110v single phase AC voltages. Where as in industries
and power stations, it's going to be up to 11kv and for transmission it's going
to be above 400kv.
Electrical engineering is that the core study of the
applications of electricity and electronics, which is one among the foremost
chosen streams by engineering students. it had been introduced dates back to
the 19th century. ‘Faraday’s Law of Induction’ brought revolution in EE by
introducing new concepts of current flow. Mainly the EE study involves:
• Generation
of electricity
•
Transmission of electricity
•
Distribution of electricity
The pioneer discoveries in EE are induction motors
by Nicola Tesla, light bulb by Thomas Alva Edison, and radio by Marconi. These
innovators transformed the scenario by implementing the concept of EE into
practical devices. The specialized categories of EE encompass power generation
and transmission systems, motors, batteries and control systems.
What
is Electronics Engineering?
The Electronics Engineering revolves round the study
of electronic devices, circuits, equipment, and systems. While pursuing
electronics engineering, students learn to utilize a good range of electronic
components from analogue to digital components, microcontrollers,
microprocessors, and programmable logic devices. the precise branches of
electronic engineering mainly include:
• Analogue
Electronics
• Digital
Electronics
• Power
Electronics
• Embedded
Systems
•
Communication Systems
In 1904, John Ambrose Fleming invented the
thermionic diode tube and this invention is mentioned because the ‘birth of
electronics’. This tube worked because the foundation of all electronics of
that point, including television, and radar. Later on, transistors replaced the
vacuum tubes in 1947, which was the invention of Shockley, Bardeen and Walter
Brattain at AT&T's Bell Laboratories.
