Comment on Physics
FiniteBanjo@lemmy.today 3 months agoSo you’re saying Electronics is Electrics is Physics?
In that case Biology is Chemistry is Physics and therefor Medical Doctors have degrees in Physics. If you feel like fighting me I will await you out back.

First of all, yes - Electromagnetics is a branch of physics. James Maxwell was a physicist.
Second - Electromagnetics is not electronics. Electronics is a field that applies electricity and magnetism to make useful things.

Yeah but Electromagnetics is the DEEP magic behind electronics.
You could, if you wanted, use quantum mechanics and electromagnetic field theory to do circuit design. But unless you’re building quantum computers or doing simple circuit analysis and wanted a real challenge applying Kirchhoff’s Laws, there’s no need.
So you can use the simplified electronics model where the current (and therefore primary charge carriers) is positive.

No, That’s electrical engineering.
Electronics is specifically about devices whose properties are determined by the charge carriers themselves (the electrons or the electron holes), ie. band gap semiconductors.

So then Bridge Diodes are not Physics.

Dude, I’m sitting right now in front of a building full of people that basically study PN junctions for a living. If I tell them diodes are not physics they will be very upset.

Sorry to upset the analogue stereo repair shop but you’re not exactly Stephen Hawkings, okay?
