*summary:* -electrons flowing through a wire is analogous to water flowing through a pipe -pressure drives water flow through a pipe -voltage drives electron flow through a wire -"current" is the rate at which electrons flow past a certain point in the wire -current depends on the voltage and resistance -different material offers different amount of resistance to electron flow

Dude, bullying isn't a big deal, all you have to do is just give the bully a thick punch in his face, a good punch, only 1 punch is enough, and they he won't bother you anymore, stop being afraid of him, don't be afraid man the fuck up grab your balls stand up high raise your head and say I'M A MANLY ASS MAN and then go to school, and if he slightly bully's you SLIGHTLY . simply go up to him and give him a good thick punch, all your sissy problems will be over, stop being afraid, i myself have been bullied for most of my school years, but i now know that part of it is my fault because i was too afraid to stand up for myself, now nobody bullies me.

This is simply awesome! I just developed an interest in electronics, bought a "beginner's book" (and components kit) and I was left with more questions than answers. The writer provided very convoluted explanations, assumed knowledge I didn't have and I was left confused and a wee bit frustrated. Thank goodness for your series.

[@nguyenminhtran1760]

I love how you use water to give a mental picture of the differences between Voltage, Current, and Resistance. My kids love it. I actually told my kids to think of Resistance like a faucet's shutoff valve. We don't change the size of the pipe (wire) but by adding a shutoff valve we can adjust the flow of water through the pipe.

[@AdeleandHarmonyband]

Hi Tony. Man, I'm really enjoying these electronics tutorials and how you explain things for a not so electronically inclined person like me.

[@zhouwu]

I worked out this relationship between the potential energy of water height and the potential difference in electricity, I worked out the similarity between water flow rate and the electronic current, but yours is the first intuitive way to relate the difference between macro fluidics Vs micro fluidics to low resistance circuits and high resistance circuits. Thank you, sir. I really appreciate it.

[@NorthernKitty]

Instead of "size of pipe", I would suggest using an analogy of valves OR of materials filling the pipe (sponge, sand, etc) to describe "resistance". Either analogy would slow the flow rate even as the pipe remains the same size. It might be less confusing since, as you said, we don't actually change the size of the wire in order to change the current.

[@Acecool]

Most teachers get a job to have a job; they aren't educators. If they can't simplify a topic to the base terms and explain it any number of ways tailored to the student who asks about it, or in a general way to the whole class.. then they don't know the material and are likely regurgitating from a book. Now, in school, in the US namely, most teachers tell you to memorize stuff. But as human beings, our memory isn't the best and for most people it changes as we age. The more you understand something, the more it is set in stone and easier to recall. Most teachers only regurgitate what is in the book instead of letting the students read the book, and explaining it a different way ( which would provide 2 distinct ways to recall the material ). Instead, they use one method, making it harder to recall. An educator will have the book, and give at least 2 different explanations along with examples.

[@mrdhksan]

Fantastic! Here’s another analogy and a quick summary: 1. There are TWO Tanks, T1 and T2. 2. They each contain the same VOLUME (quantity) of toy cars. VOLUME = VOLTAGE. 3a. T1 has a FAT pipe connected. FAT = LOW RESISTANCE (like an 8-lane highway). 3b. T2 has THIN pipe connected. THIN = HIGH RESISTANCE (like a 1-lane highway). 4a. T1’s FAT pipe allows MORE cars pass to along the highway per second or per mile 4b. T2’s THIN pipe allows FEWER cars to pass along the highway per second or per mile 5. The RATE at which each tank’s total cars pass along their respective highway is the (NUMBERS OF CARS ON ALL LANES OF THEIR HIGHWAY) / minute or mile 6. RATE = CURRENT 7a. T1’s RATE is HIGH 7b. T2’s RATE is LOW So ... Same VOLUME (quantity) of cars + FAT highway -> High flow RATE Same VOLUME (quantity) of cars + THIN highway -> Low flow RATE The End. You’re welcome.

[@TheSouthernStocking]

Great series, hope you find the will to continue it.

[@watsoft70]

I know that there are similarities between the flow of electrons and water, but IMHO, it makes it harder to understand, probably because you tried to explain each aspect. It might be better to show and work through a plumbing example from tank to tap, then identify the similarities. Thick pipe/thin pipe, not a great example, better identifying the tap as the resistor, or if you have to, introduce a lot of elbows in the pipe. This is meant to be constructive criticism. I appreciate you taking the time to produce this and will follow the series to the end.

[@epochseven4197]

Just to add on to your comment, I think the water flowing through a pipe analogy is best way to conceptualize the flow of electrons in a wire. That said, I agree with you that it can get confusing when you go back-and-forth between the two so how you present this analogy is important. What I found helpful was a video in Khan Academy titled "Resistivity and Conductivity" that also uses the water pipe analogy but explains it in a way that is less confusing. Not a knock at all to CodeNMore's tutorials (which I greatly appreciate), but he even says himself that we should consult various resources when learning things like these since different learning material will present the same topics in different ways, and hopefully one of those ways will be more understandable for some of us.

I really enjoyed this video (and the series so far). Are simple enough to get easily understandable and in the same time they contain enough information to feel that you learned the things you were looking for. I wish school or even uni was that good when I was doing subjects about electricity/physics. I remember that were my most hated subjects (purely because of the overall presentation in books and how teacher were approaching it). But now I am so hyped to learn more.

[@ziul911]

First of all bro, thanks for the great content. I've been searching for introductory electronics videos and yours are just as good as all classes should be. I think that the current has been a little bit bad defined. In physics when we talk about a flux it's basically an infinitesimal area times a number of entities. In the case of the current it would be the side area (sorry, I don't know the right term for this in english) of the wire times the number of eletrons. So, if you get a larger wire (one with a bigger radius), you'll be able to transport more electrons an enhance the current. Furthermore, the definition of resistence is r = (lenght of wire)/(side area of wire). Therefore, again, the larger the wire, less resistence you'll have and because of that, more current

[@whisperingsage]

I first learned about resistance when my first husband's extension cords all over his floor melted and made stinky smoke in the trailer. I learned that if I didn't want too hot a wire, to get bigger wires. That was my take home lesson. Or my prevent the home from burning down lesson. And yes, on solar, we (second hubby, still knows less than me about it) still use a lot of extension cords and it's hard to find 12 AWG or larger extension cords.

[@mohshar8074]

Thanks for these vids ! Yup , a larger wire means more electrons and current but the water example is a false one . The same volume of water per time unit passes in a smaller tube under the same pressure , which requires the water to move with a higher velocity ( According to the continuity equation ).

I like the way on how you educate every viewers in a fundamental theory using a practical illustration to fully can recollect a scenario of lessons in the beholders eyes. For this bec i love studyings eventhough i have a sort of knowledge about electronics well, education is a free unended process of learnings and i guess i would compare my self to such an (AC) alternating current. Wherein, when i know something new i proceed then another learning of process then alternate and then resumes my continuity current of learnings and so on... thats how i use to compare myself... and in such a way to become a (DC) lol, its a fix voltage of lsssons that i've got from the AC.

[@johnswanger8474]

So far so good. I am curious about one part of the water analogy. If volts are the "pressure", electron (water )current flows along a "pipe" ( conductive material ), and resistance works to "restrict" the "flow" of electrons, then does the water analogy continue? Restricting the flow of water by reducing the diameter of its pipe increases pressure. Will introducing a resistor have an effect similar, by increasing voltage (i.e. "pressure") in the battery?

[@BoxerDogs]

To illustrate resistance, imagine the second pipe as having the same diameter as the first pipe, except you stuff the second pipe with a sponge. So the diameter of both pipes are the same, but with a sponge inside the second pipe, there would be less water (current) flowing out. The sponge is resisting/impeding the amount of water (current) flow.

[@Pinkyyybrainn]

Second note for this video: think of voltage as intensity of electrons and current as the flow of electrons / how many electrons per second: combining them (multiply) gives you the total electrical "power". Resistance describes the environment the electrons have to travel down (wire/ pipe/ tube). Like humans, nearly all environments can be walked on but some environments can be walked on quicker, some can be run on all depending on the Resistance/ bumpiness of the floor.

[@nareshkashyap8888]

hi.. as you told resistance allow to flow current, you take an example for water presure system and told that as a outlet pipe reduce our current also reduce. but ohm's low saw some thing different that is when voltage is constant or as the resistance decreases, the current will increase. I=V/R

Sometimes when I try to assign an analogy to current and voltage I think of a specific scenerio: You want to knock down a big walk with cars/trucks Voltage and Current are inversely porportional I think. So image the speed of the cars is current and the size/mass of the cars/trucks is voltage. U can hit the wall with a rlly heavy truck and have a similar effect of hitting the wall with a bunch of smaller vehicles going faster. Either way the brute Force is the same but you can dish out the difference sizes/speeds based on the battery or total possible energy. This could be very wrong but I think it makes sense.

[@kiwinesss]

You lost me with wanting to knock down a big walk.

[@andrzejsupermocny2386]

Wouldn't making the pipe thinner make the pressure at the output increase? Like plugging the water hose with your thumb, the amount of water flowing decreases but the pressure increases? Does this hold up with electronics or was the analogy inaccurate?

[@AntPDC]

7:30 "Now obviously if we have a really smaller pipe in our water system the voltage is going to stay the same, but we're going to have less current...". That confused me. I thought voltage = pressure, so wouldn't a smaller pipe increase voltage?
