A bit disappointment to see that many don’t seem to know when the how the therm conventional current came to be because the modern use is a bit of a misnomer. I’m surprised you stopped at JJ Thompson as the discovery of electrons leaving a filament was actually discovered by Edison and is recorded in his Patent later known as the Edison Effect. Atmospheric convection currents are also what keep clouds aloft. I usually have both electrodes on my tongue (easy with a 9v, more difficult with an AA – I usually use my cheek for that). Convection currents in the air and sea lead to, Magma in the Earth's mantle moves in convection currents. What is Conventional Current Flow? When I entered tech school virtually TVs used vacuum tubes, as did much of the line powered entertainment equipment. Though some devices clearly want to say ” look… we know how it really works because we are the engineers who finally understood this stuff”… the resulting “why is this backwards” effect when encountering MOSFETS can’t be avoided… The result is the unnecessary divide between pipe smoker engineers and the fingers dirty engineers. NOAA.gov: Outreach Lesson, Convection Currents. All descriptions of electronic circuits use conventional current, so if you see an arrow depicting current flow in a circuit diagram, you know it is showing the direction of conventional current flow. So if the direction doesn’t matter then having a convention that ignores the charge carrier makes life easier.
Not I wouldn’t know what to suggest, because charge flow is a bit awkward. I would say: The taste of chili is pain.
In a circuit connected to a battery, the electrons are the charge carrier and flow from the battery’s negative terminal, around the circuit and back to the positive terminal. These forces may include: Convection currents can be modeled and described using convection-diffusion equations, which are scalar transport equations. Electrical signals of course move at a significant fraction of c, about 200,000,000mm/s.
Conventionally. Te only solid state equipment we seen come into the shop was Automotive 8 track player and and low end line powered radio/record player/8 track players units, as well as transistor table top broadcast radio sets..
I feel like I’m being dishonest when describing how a circuit works.
I’m sure a copper electrode would generate different taste from aluminium or zinc. I think it is of importance that our language and design represent reality as closely as possible Though some things may not seem like that big of a deal now, problems, workarounds and conditionals have a way of compounding into utter monsters over time. A temperature difference leads to an energy transfer from an area of higher energy to one of lower energy. I would guess that the vast majority of people here have never had a situation where it mattered one whit what the charge carrier was (semicondutor device designers, electron microscopists, electro-chemists, those designing triboelectric and electrostatic induction HV generators– primarily Van de Graff–, and old farts like me that have designed with vacuum tubes likely making the majority). Since conventional current versus charge carrier current was explained to me, I thought these are in fact two different but related phenomenon.
Off topic slightly but you can tell the direction of current flow with a battery on your tongue. Now, when it came to which way the holes were moving, that was a bit mind-altering. His iron-clad rationale? You’ll get the same results as the person using the other ‘standard’. While you may be technically accurate in the numerical values that you’ve listed, the idea that there’s is a definitive difference between flow and drift is a bit nebulous. This cycle establishes a circular current that stops only when heat is evenly distributed throughout the fluid. Can’t stand conventional current. I find cathode/anode much more troublesome.
Franklin attended his lectures and even bought Dr. Spencer’s equipment in 1746. It doesn’t care which directions are in and out, as long as you keep track of the signs. Defining a fundamental and widely used phenomenon in a way that resembles an elementary school phenomenon known as “Backwards Day” flies in the face of the simplicity and accuracy that science strives for. A byproduct of this was rationalizing current with electron current. Share your experience and opinions in the comments below.
Since conventional current versus charge carrier current was explained to me, I thought these are in fact two different but related phenomenon. So, the real current is (the word current means flow) in a direction opposite to the conventional current. I don’t think we’ll see much (if-any) change when it comes to this problem.
Conventional current is the flow of a positive charge from positive to negative and is the reverse of real electron flow. The concept of current is widely applied in fields such as electrical engineering, electronic engineering, electromagnetic theory and many other fields. jippo12 has added details to All Sky camera 2.
You could actually watch them move.
From the letters, Franklin correctly deduced which charge different objects will get, glass being charged positively and sulfur negatively, for example.
But it’s easy to remember that electrons flow against the arrows.
In the end… unless you actually design semiconductors… its not as important as just knowing… “it flows when I do this”. However, here on Hackaday we mostly deal with the current in a wire. How would you qualify the flavour difference?
Several names make no sense when discussion conventional current: I guess I just trusted that Vss is the SOURCE of the current and Vdd is the DRAIN of the current and everything worked out fine for me.
The direction of current is not so confusing. Science has moved to the point where an electric current needs to be defined as the flow of a an electrical charge.

The hot core heats the material above it, causing it to rise toward the crust, where it cools. I had a professor in physics who redefined everything to make it work with a left-hand rule instead of a right-hand. These constantly circulating cells of hotter and cooler molten rock are thought to help heat the surface.
As we saw above, the convention was that in the circuit around the cell, the current left the positive plate and entered the negative plate. You could make the pointy-finger gesture and figure out cross products without putting your pencil down. Of all things, it is something I’m generally comfortable considering as charge-agnostic.

:). *sheesh*. The electron flow itself is a slow-moving current from – to +; while the conventional current is the ‘information’ of motion which goes from + to -.
jhdewitt liked 25 A Supercapacitor Charger.
In short, hot fluids rise while cold fluids sink.
:-) (One did his graduate research in device failures due to whisker formation and electromigration in semicindutor leads.
Why do we have the convention?
There is a host of military equipment that runs on a negative voltages, the reason i was given by a military engineer is moving a large current through electrical components leads to problems with heat where as running a negative supply negates that issue.

Yessss! Probably most readers here have an EE bias, even if they are not actual EEs. Reference.
Taking into account which way electrons move can be really misleading. Herb Kirchhoff has more than three decades of hands-on experience as an avid garden hobbyist and home handyman. The cell formed by convection currents is called a convection cell or Bénard cell.
This process repeats until the air in the room is evenly heated.
Or rather, B is electrified plus; A, minus. jhdewitt liked FSAE 2014 Electric Race Car. The transference of energy is the ultimate point of interest, which is determined by the net movement of the charge carriers. I am among those who learned science (the physics) before the application of it. The Theremin Is 100 Years Old; Celebrating The Spookiest Of Instruments. Sure life was easier when the electron was they only charge carrier, however observations have shown there other charge carriers.
I was going to post essentially the exact same thing Eric. Which did you first learn?
Which could taste different.
That is all taste is anyway so I suppose taste is the right word. Don’t the electrons come out of the cathode? This would imply that negatively charged particles are attracted to it, not the vice-versa which is used in conventional circuit descriptions. As you’ll read below, it started with Benjamin Franklin. As it rises, it cools and becomes less dense than the air around it, spreading out and descending toward the equator again. Word of it, and other discoveries were spreading rapidly through letters and lectures. Conventional Current assumes that current flows out of the positive terminal, through the circuit and into the negative terminal of the source. Only thing to watch out for is which one one’s textbook is using.
(In my optimistic recollection, I don’t recall either insisting that one way was right.)
