Semiconductor diode markings.

[joebog1]

My fathers philosophy question always was:
What frequency is magnetism
IS it DC and static? OR moving at light speed and we cant measure it?
My father held degrees in engineering from all over the world, but alas was born in 1906.
NONE of his professors in France, Poland, Britain or Australia, ( where his various degrees were earned) could even consider the question ( back then).

Its funny about that, Horatio!!

With best wishes and regards to all that DONT consider me crazy,
And to those that do, as well

Sorry mods!!!
WAY off topic

All very interesting I'm sure, But I don't need to know any of this to know what a semiconductor diode does and which way to connect it in a circuit. It's also useful to know that it has a forward volt drop.

As far as I'm concerned current flows from positive to negative in the direction of the arrow. That may be carp, but it's worked for me every time.

Electrons do move, but only slowly for typical DC currents. The weak nuclear force is a completely separate issue; in electronics we are only interested in the electromagnetic force.

The usual explanation is that if you ask an electron a particle-like question it will give you a particle-like answer. Similarly for a wave-like question. This sidesteps the question of what an electron is. I think the best answer to that is that an electron is an electron. You can't break it down any further because there is nothing to break it down into. You could say that an electron is exactly like a light muon. What is a muon? It is exactly like a heavy electron!

The question is meaningless. That may be why people would not (indeed, could not) answer the question. It is like asking "How long is string?".

Getting back to diodes, they should not be marked with + or - as that is a circuit issue. They should be marked to indicate anode/cathode as that is a diode issue.
