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.

Study at my Soldermans 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.

Read these pages to understand Mains Circuit design. Safety and Protection is very important.

• High Resistance Insulation Materials
• Mains Voltage Power Transformers
• Mains Voltage Current LED Indicators
• Simple Mains Voltage monitor LM324
• Mains Voltage monitor using LM3914
• Triac based Lamp Dimmer power control

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 Mechatronics 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 part of Industrial Automation.

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.
