electrical and electronics

[prateeksikka]

hi all!
i wish to know what is the demarkation line between electrical and electronics engineering?
i.e to decide whether an application is a subject matter of electrical or electronics engineering?

Hi prateek,

I think I would draw the line between circuits including active semiconductors and circuits with no active semiconductors! As an example I consider a rectifier bridge or a diode as non active semi!
But that's just me!  8)

Electronics is fairly low powerd non-power supply type circuits, examples include audio amplifiers, radios, computers, small low voltage power supplies.

Electrical is power distribution and high power systems, examples include UPSs the mains power distribution system (national grid) large motor controll systems large transformers, generators.

Normally nowadays a knowledge of both areas is required in most jobs, for example a large UPS uses small electronic controll circuits and a large battery, transformer and electrical  protection system on the output. I've studied mostly electronics, followed by electrical and then mechanical subjects, all of them have been relevant to lots of the jobs I've done.

Hi Alun,

Don’t forget: You will need chemical knowledge too for the battery!  ;D

even in computers we need vast knowledge of electronics .world is converging dear!!!

i aways thought electrical was in electronic engineering?

 

[Alun]

No they are separate subjects, just like aeronautics, civil engineering and mechanical engineering.

 

[ECET0purdue]

i had to learn 80% of electrical before i started learning electronics

electrical prerequiste for electronics and electronics for computers! ;D
