Why would you follow conventional just because of some dude. Credibility doesn't matter that much. Electrons are negatively charged. They will come from the negative terminal. _GOD.!_ Society drives me up the wall Sometimes. I'm. Done with the internet for today.

meanwhile AC is the vibration of electrons and nobody complains that the lines aren't labeled '+-' This gets more confusing when you consider that electrons have negative charge, so you are describing a positive flow or presence of negative particles. The reason there hasn't been any problems with labeling the flow direction is that we only need to know which wires shouldn't be crossed, consistency above all. If we recolor every wire in the US, a grave inconsistency would be introduced. Every other house would have an opposite charge in its wires based on when it was built. Any modifications to existing structures would need to keep to the old system, new and old LEDs would carry opposing charge markings or some branch indicator of which system is used, power supplies would need safety measures to ensure the correct direction of power is supplied to each system. A disaster larger than switching every unit to metric overnight, seizing every electrical project in the United States for the next hundred or more years.

@@sakatababa Everything has to be assumed to an extent. Conventional flow worked and still works today in practical applications. Fact of the matter is, during the 18th century, the only thing that can be practically observed is that there are two opposite sides of a circuit and they needed a name. Without fancy observational tools from the 19th century, they had to pick one. It was practically a coin flip. People of the past weren't delusional. They had to work with whatever empirical evidence they can gather at the time. At least Ben Franklin actually experimented and observed. You couldn't do any of that yourself. You're just working off of the dogma (whether true or not) imposed to you by the Prussian Education System.

@@krish698 nope. if it did, laws of physics wouldn't be what they are. if you put the waterwheel in a river and connect the grinder to it, you get work regardless of the direction of the river. what franklin did was he just decided that the river must be flowing uphill and just gave up on ascertaining the facts. now, the question of the matter stands as do we continue to say that the river is flowing uphill if we, in the meantime, determined that it isn't the case? because that is what we are talking about. franklin didn't use that electricity in practice. he made few sparks and told people "they come from the right". very soon, a proper scientist did the work and determined that it is false, they came from the left. everyone started to exploit the information but still continued to say that they come from the right. even worse, they put the first dude, that made that assumption, on a pedestal while nobody even knows the second dudes name. as a scientist, things like that one hurt on a professional level.

Dude what are you talking about, think before you post! Its VERY HIGH not VERY SMALL. Ohm's law, the higher the resistance the less power LED is draining
@mgchemicals 14 күн бұрын
LEDs have a characteristic called "forward voltage drop," which is the voltage required to turn them on and allow current to pass through. When the voltage across an LED exceeds this forward voltage, it begins to conduct current, and its resistance decreases sharply. This behavior is due to the diode nature of LEDs, where they allow current to flow in one direction (forward bias) and block it in the opposite direction (reverse bias). Once the LED crosses that forward voltage threshold and turns on, its resistance drops significantly, allowing a substantial amount of current to flow through the LED 😉

I‘m confused by 0:26 where Voltage is V instead of U. Nevertheless an interesting fact
@mgchemicals 14 күн бұрын
This got mentioned a lot in the previous video I posted. In Ohm's Law, the symbol "U" is sometimes used to represent voltage, especially in European countries and in certain contexts within electrical engineering. This is analogous to the more commonly seen "V" in Ohm's Law. The choice of symbol depends on regional and disciplinary conventions, but both represent the same physical quantity: electric potential difference. However, since the SI unit for voltage is "V", that's what I've decided to use. I am aware that this contextual preference has caused some slight confusion and I'll keep that in mind moving forward!

In some European countries, the symbol is used to represent voltage. Here in North America, we use the letter V. Ohm's Law states that 𝑉=𝐼𝑅 where 𝑉 (or 𝑈 in this case) is the voltage, 𝐼 is the current, and 𝑅 is the resistance. So, when using the symbol 𝑈, Ohm's Law can be written as 𝑈=𝐼𝑅 😉

No, the grease has not adhesive strength and will not bond the electrode. Typically, people using a grease will secure the part with screws/clamps and just use the grease for thermal management at the interface. If you need bonding, consider instead a product like our 8329TCM which is an adhesive.
