Basic Electrical Circuits
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. The
Computer was a 386 40MHz with 40MB HDD. You can see an Dot
Matrix Printer on the right.
