I never thought of that.OR, you teach them that the arrow looks like a letter "A", for "Anode".
They actually remember that.
Better yet, the other end looks like a "K" for "Kathode".

The standard check valve symbol I always saw when I was working hydraulics looked like a ball in a sideways V. But as I go out and look now, I definitely see a symbol much more like the electronic symbol. Maybe the military used the one I was familiar with for some reason (such as teaching people with an 8th grade reading level how to maintain high-performance aircraft).Unfortunately the standard check valve symbol used for a diode, is based on Ben Franklin's assumption that electron flow was from +ve to -ve.
Hence it being technically backwards facing.
Anyone that came through the tube era often intuitively tends to think in electron flow (cathode to anode).
Max.
I can work in both, but if I have a device that really calls for thinking of electron flow, I find that I will think of electron flow for that device and conventional flow for the rest of the circuit and not find it at all confusing. But if I have to analyze a simple circuit using electron flow I find that I have to be very explicit in what I do to avoid screwing up.I can think in both, but I suspect if you come across a tube circuit you think in terms of electron flow, no?

I couldn't agree more -- and it is a complaint I have made time and time again. When I was a Physics undergrad, the test equipment we had available was antiquated and temperamental -- you spent half the time figuring out how to trick it into working (or outright repairing it). That was very arguably the most educational part of most of the labs!What drives me crazy is students at the uni who have access to the school's digital scopes, and they have no idea how to adjust them manually. Everyone just hit's that stupid "auto-scale" button and wonders why it doesn't work when the trigger is off. I always try to encourage them to adjust the knobs by hand and change the scales to make it look the way they want it to. I can't stand it when students insist on using the auto-scale button instead of learning how the scopes actually work.
In name, yes but not by symbols. N-channel MOSFET pins are SOURCE (source of electrons) - the more negative terminal. And DRAIN (of electrons) - the more positive terminal.is there any parts out there that uses the electron flow instead of the conventional flow ?
Pretty much sums it up for me also.I can work in both, but if I have a device that really calls for thinking of electron flow, I find that I will think of electron flow for that device and conventional flow for the rest of the circuit and not find it at all confusing.

The naming is not "reversed by convention", but is quite consistent. The source/drain and emitter/collector refer to majority charge carriers.In name, yes but not by symbols.

The protocol is reversed for P-Channel MOSFETs by convention (corresponding to the inversion on PNP transistors).
I just wanted to be sure the OP did not expect the Source on a P-channel to also be the more negative (source of electrons).The naming is not "reversed by convention", but is quite consistent. The source/drain and emitter/collector refer to majority charge carriers.
The thermionic diode is a good reminder - the electrons are emitted by the heated cathode.Hi
Does a diode arrow point in the conventional current flow or the electron flow ?
