Electrical and Electronics :
Electrical Engineering encompasses
Everything in Electronics.
Communications, Computers etc. are
further specializations of
Electronics. So it is best to Identify
Electrical Circuits with Electrical
Designs which excludes Active Devices.
It can include Electronic Products in
the form of wireable modules.

Basics and Circuits
FAQ
So House and Factory wiring,
Appliances like Ovens, Toasters, Power
Generation and management; all
these are electrical. Motors,
Generators, Connectors, Relays,
Contacters and Circuit Breakers are
Electrical Components.

A Radio or Power Inverter is
Electronic. When an Inverter or
Electronic AC-DC Motor Drive is used
in a Control panel or Power Supply
system, that integration is shown as
an Electrical Circuit. I feel Simple
Consumer Electronic Circuits using
Diodes, Transistors, SCR, Capacitors
and Resistors can also be taken under
electrical circuits; when they are
used in Mains-Power or Household
Appliances. Solar Energy related
circuits also can be studied under
Electrical Power Circuits.

Circuit design
In Electronics RF-Microwave and
Communications is a specialization
area, Computer Hardware, Software,
Internet form another major domain.
Networking and Wireless data
communication overlaps both the above.
Power
Electronics and Instrumentation are
fundamental domains needed for many.
Industrial Automation with Process
Control Instrumentation is unique, but
is supported by the fundamental
domains. Many more finer areas like
Robotics and Medical Electronics have
a much sharper focus.
Below is a Electrical Control Panel,
It has a Strip Chart Recorder which is
electro-mechanical, It has a PLC
Inside. A handheld PLC Programming
unit. The computer is showing the
Ladder Logic Program. PLC is based on
a embedded uC. The DIN Controllers are
Analog + Digital circuits. So you see
it is a Electrical Control Panel with
Electronics and the PLC Ladder Logic
means, Software too.
This is a PID Controller based Control
Panel using a PLC from GE Fanuc
Automation. The Computer was a 386
40MHz with 40MB HDD. You can see an
Epson Dot Matrix Printer on the right.
