Back in the late 1970's, I put in a whole semester learning about resistors, and learned about 90 percent of that semester in this video! Plus the resistors back then were the carbon variety, unless you worked with industrial (1 percent) resistors. They were blue colored with black value numbers on them.

I went to Naval Avionics School in 1972 and all I remember working with resistors that were carbon and wire wound. I worked in a TV repair shop a few years before that at 16. We actually had some electronics classes in the high school I went to. They sure don’t teach that in high school anymore. I worked in electronics all but a few years of my work career. Worked on some cool things from oil well logging tools for 8 years and then 31 years in telecom working on digital transport all over Alaska and some overseas.

I believe the resistor placement doesn't matter. This is as you said because it creates sort of a barrier slowing down the flow, and it'll be slowed either before or after the LED. If it's slowed after the LED there's still that sort of "Jam" no matter what. I also believe the resistor shown has a resistance of 1200 Ohms with a tolerance of + - 2%.
@Gengh13 Рік тому
Correct on the placement of the resistor in the circuit, all elements in a series circuit get the same current, no matter their position.
@KhunThomat Рік тому
I had also determined 1.2k +/- 2%. Unfortunately, the color code of low tolerance type resistors is often disambiguous - that is why I always measure them to be sure...
@TheGlassgubben Рік тому
I would use gauge invariance to argue that what is down or up flow is only a question of definitions and have no physical significance. I think this is mathematically equivalent to your explanation, even in transitive states.
@Subat0micR0gu3 Рік тому
I also determined 1.2k ohms. That's because when he asked the question in the video, he had the resistor one way, and then when he answered the question, he flipped the resistor for some reason. That meant we looked at the colored bands backwards. I'm not sure if there is an easy way to know which direction is the right one, but for a training video, it would have been nice to have it lined up properly.

@matthewlozy1140 9 місяців тому
Water and electricity aren't a perfect analogy.
@Canaverde2 9 місяців тому
Your assumption is only valid if the speed of the water pre-obstruction was constant. But, on that model, if you cover the whole channel, the speed of the stream would be infinite, which is obviously impossible. So, the higher the resistance (the covering of the channel), the lower the current (the water stream after the covering), for the same voltage (the height of the water pre-covering or pressure).

You forgot temperature coefficient, which is usually indicated after the tolerance band. There are a lot of applications where a low tempco is more important than a low initial tolerance. Carbon comp resistors are still relevant in high frequency applications where any stray inductance is undesirable.
@d614gakadoug9 7 місяців тому
One of the things that drove me crazy when making the transition to surface mount is the rather dismal tempco of common 1% SM resistors - typically ±100 ppm/K. I was used to 50 ppm with the Philips leaded resistors I generally used. If you want decent tempco in SM resitors you're into 0.1% or better tolerance (which I often did want along with low tempco). Carbon comp _are_ low inductance but they also tend to have relatively high capacitance, so you lose on one hand what you gain on the other. They are a lot more tolerant of transient overload than film types. Their excess noise (i.e. beyond Johnson noise) can be a problem. The reality is that resistors demand careful attention when you are doing demanding work. I ran across another resistor video a while back, talking specifically about 1% leaded resistors available on ebay. One commenter insisted that you should be able to make your circuits work with 10% tolerance parts. Sigh!
@petersage5157 7 місяців тому
@@d614gakadoug9 What was the context of that other comment? Current limiting for an LED? Pull up or pull down resistors? Biasing a transistor or valve? With very few exceptions (usually frequency-dependent or high resolution current sensing, and you're likely to know _when_ you need the tighter tolerances), it's good practice to design for 10% tolerance and specify 1% resistors and 5% capacitors. The common examples listed above typically work just fine even is a resistor is 20% out.

Most wire-wound resistors don't use nichrome wire. Nichrome has a high TCR, so if precision is needed, manganin is used instead. With nichrome, the difference between cold and hot can be as much as 2:1. For small encased resistors, manganin is definitely the norm. Nichrome is more corrosion resistant and can operate at higher temperatures so it is a good choice when lots of power and long life are the priorities and actual resistance isn't too important. It is often used as an "open" resistor where the wire or strip is exposed to the environment. That lets the temperature go higher as nichrome is reliable up to 350°C, beyond most insulator's capability, and the thermal conduction to the air is better without a coating. The downside is corrosion will increase resistance over time, but is less of a concern in massive resistors where a little loss of thickness is less significant due to the element thickness. Nichrome is a common braking resistor for moderate sized drives where the current isn't too high. Stainless steel is also quite common, used where lower resistance is needed. For example, most rail applications use stainless steel braking resistors.
@d614gakadoug9 7 місяців тому
Manganin is very commonly used in "shunts" for measuring current. I used manganin wire for current sensing in some DC-DC converters back in the days when there were far few suitable off-the-shelf low value resistors than there are now. I have some braking resistors that I bought to use as test loads when I was doing power supply design. I have no idea what material they are. They are edge wound with metal about 2.5 mm thick and 12 mm wide and are about 45 cm long. They were intended for transportation use.
@johncoops6897 Рік тому
Regarding the multiplier, it is easier to use the same colour codes as the main digits. For example Orange Orange Brown is 3, 3, 1. So, 33 and ONE Zero = 330 ohms. Orange Orange Black is 3, 3, and ZERO Zeros = 33 ohms. This is much easier than using a "multipler" since you don't need to look up the chart to find a multiplier, then use math to multiply anything... instead just add however many zeros is applicable. The exception is lower value with Silver and Gold multipliers, where the chart is needed.

@Kesuaheli 11 місяців тому
While this is correct, I have to say that the multiplier in the lookup table just means "times ten to the power of n", where n is the multiplier number. From ◼️ black or "0", with ×10⁰ up to ⬜️ white or "9" with ×10⁹. With the special cases of 🟨 gold with ×10⁻¹ and ⬜️ silver with ×10⁻² Of course in the decimal system that just corresponds to the number of digits you shift the decimal point. That's the point why they've chosen these numbers anyways. Tipp: If you have difficulties to memorise which way around the gold and silver one are: think of medals. Gold is 1st place, so "1" or "×10⁻¹". Silver is 2nd, so "2" or "×10⁻²".

I think it's worth mentioning that the potentiometer type designation with letters in 15:18 varies depending on the country and manufacturer. For example, in Europe, "A" means linear and "B" means logarithmic. Additionally, except to these two types, there is another non-linear one, which is inverse to logarithmic and in Europe is marked with the letter "C".

I have a four year degree in electrical engineering. If they got rid of the fluff and taught us things we actually needed to know, it could have been one year. Some professors need to watch this video and ask whether they are giving their students the best style of education.

Paused at 24:23, interesting to see that W is calculated like this. I'm a learned electrician, and I calculate basically 9V*0.9A=8.1W (yes, I know, first calculate your A with Ohm's Law), nevertheless, really interesting video. Definetly a blast to the past for me on this one! Really, really well explained! absolutely a masterpiece, wish I had this info when I was back in school, like 20 years ago :D
@AlmaTheElder Рік тому
If you think about it, you're doing the same calculation once you break it down. As you know, V=IR. So when you do V*I = P, you're doing R*I*I. As I*I = I². Therefore your V*I = P is the same as their R*I² = P
@ReaperSilently Рік тому
@@AlmaTheElder True that, can't agree more. You do realize that people will start looking at these comments and go like, wait, what :D Although, I'm pretty sure the average person watching this will be knowing what and how. Also, an interesting remark I noticed: Not sure where you're from, but the symbolisation is interesting on your side ;-) here its U=I*R. Don't ask me why they changed the V to an U here, but hey, I guess they wanted to differentiate I guess? Have a great day ;-)
@GenaTrius Рік тому
I find it easier to think of the multiplier as "the number of zeros after it." If you think about it, that's what it is in both band code and normal surface mount code.

The color bands on those metal film resistors are hard for me to decipher because I never know which end of the resistor represents the first significant number or the tolerance. The values are very different depending on which end you start from, which is frustrating for me as these are my preferred type of resistor.

I worked in a factory from 1988-1997 in Huntington, Indiana. It was called Memcor-Tru-ohm. We made resistors and rehostats. From welding the little lead wires on the caps on the end of the ceramic tube, called the capper. Then they went to winding department, and depending on what the customer wanted, that determined the gauge of copper wire that was used, how many times it got wrapped. Kinda reminded me of a sewing machine/lathe/welder combination. Winding rehostats was a totally different machine, but the same ohms law applies to rehostats too, wire gauge, times wound. Rehostats were more labor than resistors. They had to hand weld the connecting bands on before winding, then it had to get cemented to its ceramic base after coating and firing the glaze. Bigger resistors had to go through a hand brushing department to remove the ceramic coating after being dipped in mud slurry and allowed to dry 24 hours. Then they got put through the oven and baked. After baking, the terminal was sandblasted to remove the ceramic. Then it was stamped or color marked, packed and shipped. The smaller resistors got coated too, but in an automated machine that was 20ft long.
