What's the Distinction Between Electrical and Electronics?

Click For Summary

Discussion Overview

The discussion centers on the distinction between the terms "electrical" and "electronics," exploring their definitions, applications, and the characteristics that differentiate them. Participants examine various perspectives on the nature of devices classified under each term, touching on concepts from engineering and practical examples.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Technical explanation

Main Points Raised

  • Some participants suggest that "electrical" refers to mechanical devices using electricity, while "electronic" pertains to devices that process information with small voltages.
  • One participant questions the classification of devices like radiant heaters and incandescent light bulbs, arguing that anything using electricity could be considered electrical, leading to ambiguity in definitions.
  • A participant recalls an instructor's explanation that electrical devices operate at low or no frequency, whereas electronics operate at high frequency, although this view is contested.
  • Another participant asserts that frequency is irrelevant to the distinction between electrical and electronics.
  • Some participants differentiate based on voltage levels, stating that electrical engineering deals with higher voltages (kilovolts) and electronics with lower voltages (milliamperes).
  • Examples provided include electrical engineering applications such as mains supply and appliances, contrasted with electronic engineering applications like timers and audio equipment.
  • One participant defines "electronic" as involving current flow through devices using semiconductors or vacuums, such as transistors and vacuum tubes.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the definitions and distinctions between electrical and electronics. Multiple competing views remain, with some participants challenging each other's perspectives.

Contextual Notes

Limitations include varying interpretations of what constitutes "electrical" versus "electronic," dependence on specific definitions, and unresolved aspects regarding frequency and voltage classifications.

What is the difference between the words " electrical " and " electronics"?
 
Engineering news on Phys.org
The difference is subtle, but typically the word "electrical" is used to describe something mechanical which uses electricity for power, such as an electric motor. The word "electronic," on the other hand, is typically used to describe devices which process information, typically using small voltages.

Hmmmm. So my radiant 'electric' heater is neither. It has no moving parts (not mechanical) and does not process information. Same would go for an incandescent light bulb.

Anything that uses electricity can be considered electrical. From here on is where it gets into a gray area.

I may not remember this correctly but it seems I was told that in order to qualify as electronic the device has to control or manipulate the electric current at the electron level such as a transistor as opposed to a set of contacts. Many people don't consider vacuum tubes or any electrical technology older than the transistor to be electronic or 'solid state' but some are. An incandescent light bulbs behavior can really only be described by discussing electrons. Technically you could say the same thing about a set of contacts, so who knows...

My 2 cents, probably worth less than that.
 
well when the first day i entered into the class , our instructor asked the same question
but he answered on the basis of frequency as it recurs to me.
electrical things operate at no or very less frequency whereas electronics operate at high frequency
 
I would say that frequency has nothing to do with it.
 
Back in Engineering School we used to say that electrical deals with kilovolts, ohms and amperes and electronics deals with volts, kiloohms and milliamperes.
 
It's generally known that electrical is for mains supply and up. And electronic is for lower voltage circuits.

Examples of Electrical Engineering: Mains loops, heating, lighting, electrical appliances, vehicles, industry, etc - basically anything using at least mains cable wire.

Examples of Electronic Engineering: Timers, radio, audio/video equipment, gadgets - basically anything using wire measured using awg (e.g. 28awg)

Then there's micorelectronics which refer to chips/IC's and programming, etc.

The difference is this: "Electronic" means that electrical current flows through devices that use either semiconductors or a vacuum: eg, vacuum tubes, bipolar transistors, FETs, etc.
