Why is the resistor connected to the Anode (+) on the diagram, when on the bread board it was connected to the Cathode (-)? If you could explain why that'd be great as I want to make sure I have a decent understanding of the fundamentals. Great fan of the series btw, gonna soon be studying electrical & electronic engineering and this is giving me a head start.
I know I'm late, but it doesn't matter where you put the resistor, at least in this simple circuit.
@@edwards5036 I have the same question. On the bread board to get from the battery negative to the LED you had to go through a resistor. In this diagram the battery negative is connected directly to the LED.
Nothing is boring for the beginner that wants to learn, it's awesome.
fact
Yeah facts
First thought that entered my head here, this is all fascinating.
this is all good
I love it
At the beginning I was "thinking" about getting into electronics, but now I know I'm going to. I'm really looking forward to the next episode!
I have spent months researching into electronics and found a fantastic resource at Gregs Electro Blog (google it if you are interested)
BORING!? what the hell are you talking about? I really like the way you are teaching us noobs step by step, I'm a graphic designer and I really want to learn and so far it's been amazing, I'm old and stupid and you make me understand it all, and english is not even my native language! that's how good you are sir. Seriously thank you.
I am just getting started in learning electronics and here I am at age 68. I am a retired commercial pilot. I LOVE to learn new things and this is exciting to me. Your videos are very "short and sweet" making them interesting and NOT a sleeping pill !! Thanks and I look forward to watching the entire series..
Wow my dream was to become a pilot but unfortunately I couldn't afford :(
21 yrs old, now building blockchain networks for my government projects and ended up here to understand how my shitty code works
If you're an electronics engineer or an experienced hobbyist you might find this series boring, but for the complete newbie your explanation of the basics has been spot on so far. The shorter video lengths makes it easier to view as many or as few topics as you want, plus the short format keeps you on topic without getting lost in a bunch of theory that is beyond the scope of the lesson. Well done. Almost 60 years old and you are definitely teaching this old dog some new tricks.
This is so clearly explained that could put many schools to shame. Thank you!
You said that the series has been boring so far. Not at all. This has been the best series as you don't skip past many things as other teachers do. You introduce each thing that is used which is what I've needed.
Not boring at all! I started this series feeling that everything would be beyond my understanding, but you've made it incredibly easy to follow. I'm loving this series!
same
"...Pretty boring so far..."
If only my teacher was this boring, i may already understand everything you explain. Man this is fun, well for me it's bloody fun. You make learn basic electronics fun.
I completed 4 years b.tech EEE there also i not learned this much you explaining that much clear
Thanks bro
I am looking forward to your videos
By far the best electronics explanation videos I have seen yet. Great job man!
These tutorials are great! Concise and informative, and you don't stutter. Keep it up!
In this particular circuit example, should the resistor symbol be on the other side of the battery, since electrons flow from negative terminal to positive terminal?
NO! You are defiantly not boring, you are properly the best and most interesting teacher on electronic on TH-cam!:-)
Really really many thanks!!
Thank you for the new episode
Looking forward to the next one
Been waiting for ages
Awesome! I've always been wondering about this but never had a foundation of knowledge of how electricity works in order to take a structured approach at making sense of schematics. This should be fun. Thanks for sharing info. GL - never give up!
I love these little information nibbles; extremely easy to understand, and I have practically no background in electronics.
Thank you for your playlist. This is awesome and I've not found a video that explained things easily as this. Thank you very much !
Great instructions! Simple and easy to follow along! Thanks 👍🏼
Short videos help us concentrate and give us the straight content .
Big thank you
It has all been very well explained and straightforward, you are doing a fantastic job of this. Thank you!
been waiting for this and it's worth the wait. thanks for the great tutorials.
Just found your videos and love them. Using this to learn electronics so I can go on to learn more about computers below the abstractions. Schematics are kicking my butt. So this is not boring nor are any of the other videos. I’m hoping there is a video dealing with when the schematic doesn’t not have all the wires and doesn’t look like the actual circuit
This is SO well put together.
Heading to lesson number 12, I have fixed TV's in the past with no electronics knowledge , THANK YOU you are doing good work, GOD BLESS
Great videos lot of thanks. One question related to this circuit, what if the resistor is connected to the negative terminal. Will there be any difference. Is it necessary to connect to LEDs anode terminal? Thanks.
I feel like your doing a great job. Especially for what the lessons cost... $0. So we are getting way more than we pay for... also you do a great job of explaining things without talking down or treating us like we are stupid.
Thank you
Finally^^ i was searching so long for a schematic video because there is basically none...
At the start of this video you say “I know this series has been pretty boring so far”
How wrong you are! This series has been really enjoyable. You’re an excellent teacher. Thanks 🙏
Hey man you are an awesome teacher insofar as you don't try to cram too much stuff into one lesson. I'm sure these were me a while ago but I M enjoying these videos very much. Thank you for taking the time to teach fools like me. I learn differently than other people. But you're making it easy for me and I thank you for that sir.
I don't think it's boring. I love it!
Ive learned more here about physics, then my junior year physics teacher ever taught me. 10/10 quality and interesting
Very interesting not boring I watched 12 in a matter of hours good stuff 👍.
Shouldn't the resistor be on the other side, as it flows from - to + ? Thanks
it can be connected anywhere in the circuit.it doesnt have a positive or negative pole
I was thinking that. Shouldn't the current run across the resistor on the way to the LED? what sense does it make to have a resistor on the way back to the battery?
My only confusion so far. Your bread board example had the resistor on the negative terminal, whereas it was on the positive terminal with the crocodile clips and also on the schematic. Was the bread board wiring a mistake?
Thanks for the video. Can you please tell what are the two more vertical extra lines in the schematic other than + & - terminals?
Another great episode!
I remember back in high school electronics in the 90s my teacher preferred the dot vs no dot for connections, but I just loved the cartoon aspect of drawing the little hop.
Hi there. Can you tell me what they call the male pins that you have made the connecting wire with that inserts into the breadboard. I cant seem to find them? Thank you and Brilliant tutorial. Brilliant!
I love this stuff..how much time do you think it will take before someone can become somewhat proficient at electronics? Has anyone here completed all 30 or so of these tutorials? if so I would like to hear how much this has helped..thanks
Whoah!!! This series has not been boring, it has been really informative and interesting. I've watched every episode so far and will probably watch them all, don't put yourself down mate, these are excellent.
Does it matter if the resistor is before or after the LED? In the schematics here the resistor is in front of the LED (from the point of view of the positive terminal of the battery), while in the actual practical application in the "bread boards" video, the LED was connected directly to the positve rail and the resistor afterwards. This makes me think it doesn't need to be "in order" as long as it's being "brought down" before the circuit is closed?
Thanks for this video sir 💐🙏👍
Thank you so much
question: By episode 15, do i need the supplies mentioned in episode 9? Or can i just watch past that without anything?
dude this was really helpful
This might be irrelevant but i just remembered it so i am going to ask anyway. I remember when i found a small lamp toy thingy with 2 stripped wires once and for some reason i touched the cables to my forehead and the bulb lit up. This would also happen when i would press my thumbs with a relatively low pressure on the wires as well (each thumb on a different wire). Does that mean our body "produces" voltage?
I have a question, what is displayed on the schematic and what was on the bread board was different, does it matter where you put the resistor, on the positive or negative terminal, also does the current not run in one direct? so it needs to be connected a certain way? Sorry iam just trying to understand as best as possible, any feedback would be greatly appreciated.
correct me if I'm wrong please: Current flows from negative to positive right? And I thought the arrow of a diode shows the direction current CAN flow, and the straight line shows the direction it CAN'T flow. So isn't it backwards in this schematic?
So when the wires cross, before putting a coat around it, would the exposed part be like this: (the exposed part is the +, or the intersection)

- + -

This isn’t boring trust me I am learning a lot from this I’ve always wanted to be a coder but it was way to hard for me to figure out, then I just thought of how I wanted to build robots then code them so I started to watch this
I have a question Suppose i had a wire connected to battery and that wire is connected to three other wires through a junction how does the current and voltage gets distributed?
And Great videos Dude..
The voltage will be constant , but the current will differ depending on the resistance of each wire.
great job!
Loooove your videos! I would actually pay if ever you would sell some more advanced course!
If I understood the previous videos of your brilliant project right, the resisor is placed in the wrong place in the scheme, no? Shouldn't it be between the '-' of DC and LED?
I'm a little confused, shouldn't the current flow from the negative terminal to the positive terminal?
Hi! Maybe an odd question but what software do you use to make your drawings?
very helpful! TY!
Its been years since i took basic lectronics subject, but i was never told that those wires aren’t connected!
So that was why i always messed up solving!
it's not boring actually I learned a lot from your tutorial than in school.
do resisters have anode+ and cathoud-
In the earlier videos you put the resistor between the negative terminal and the Diode. but on the schematic it's on the positive side. Why is that?
hello, i am a beginner and your videos are very helpful, i would like to ask , why the resistor in schematics is on the positive side? as i have learned the electrons are moving from negative to positive direction, shouldn't be located at negative wire side? :)
5 years too late but whatever you probably already know but anyway; it doesn't matter for the most part, as long as it is connected to your circuit, it will limit the amount of electricity flowing through the circuit.
I know this must be a stupid question, but I thought electrons flow from negative to positive. If that's the case how come the resistor in this schematic is between the positive terminal of the battery to the LED?
Thank you! for teaching schematics, rather than using your pictures all the time!
THANK YOU!!!!!!!
I have a question regarding the electron flow and the resistor placement. Since the electron flows from the negative to positive terminal, doesn't it make more sense to put the resistor between the negative terminal and the diode, instead of between the diode and the positive terminal? From what I understand, the resistor decreases the current value, which is what we want to prevent blowing out the LED diode.
The resistor can go in either position. It's really about the differential between the - and + terminals; in other words, the current coming out of and going into the terminals will always be equivalent. As a result, no matter where the resistor is placed, it is still going to handle the same voltage drop across it in either position.
CodeNMore this took me a few days to process but I get it now. Thanks a bunch!
Thanks. I've looked at a lot of videos, and nobody else has clarified how connecting wires are supposed to look.
Hi, For battery we have one +ve and -ve charge, so in schematic we should show one long line for +ve and one small line -ve, why do we need to show two long lines for +ve and two short lines for -ver. Im confused with battery representation. pls clarify my doubt.
Each set of a long & short line represents one battery (say 1.5V). When it is drawn like in his circuit example, it means 2 batteries connected in series, that is one after the other. If each battery is 1.5V, the circuit example would be 3.0V
Ha! Your resistor was behind your LED on the breadboard, so this isn't EXACTLY like your circuit ;-# So far these video's are amazing :)
what is the flow of electrons in a circuit that is the direction of current for positive to negative or vice versa. and what is thje best way to put resisror
+Ali Khan electrons technically flow from negative to positive, however it was originally though to be from positive to negative (this is why all of the schematic symbols mostly show positive to negative). This still works today because even though electrons flow - to +, it can be though as losing electrons going from + to -. Anyways, as for your resistor question: resistors aren't polarized and aren't a form of a diode, so you can place them any way. An LED, for example, you must place in the proper position, as some components have this requirement.
+CodeNMore I think the question is: if current goes from negative to positive, shouldn't the resistor go between the negative pole of the battery and the cathode of the LED? That way, the resistor will do its job before the current flow reaches the LED. In the present form, it seems that the current gets to the LED without any resistance. Thanks in advance.
Why wires need to connects - and + of a battery? Can't I only connect the + of the battery to the - of a component? (Like a led) please help me :(
i guess thats probably because the LED has a certain voltage it can take...forward voltage.if you are using a 9v battery, its too much for LED.so need a resistor to cut down the amps other wise it will blow up the LED.( remember the water tank episode)
If electricity travels from minus to plus, what's the point of putting the resistor after the LED?
According to my logic it would just be ignored if it's put after, since the electricity has already traveled through the LED, before it actually went into the resistor.
I assume I'm missing something here? :P
The Shroom
good question. I was confused about this as a beginner too. but then I read that current doesn't literally flow from one ditection to the next.
it's simply how it's explained to beginners because thry don't want to overwhelm us.
hence the resistor simly limits the total amount of current in the circuit not just in one direction
@Elexie Munyeneh -
Thank you for explaining this - I was wondering the same thing.
Current does flow from negative to positive, however it's like a congested highway. If anything in front is moving slow, everything behind is forced to move slow too.
And another important info:current travels the path of least resistance
I think it is because the current flowing through one branch(wire) is always the same. To measure the voltage from one point to another, you multiply resistance by amps. It does not matter if resistor is on one side or the other, what matters is that it is in that branch, as you are using the resistor to minimize the voltage so it does not fry LED. (electricity is not changing, only the voltage)
however, if you have 2 parallel wires, current will split in two.
This series is making my failed trigonometry attempts make more sense
What about the DC direction ...
Isn't the negative side of the battery supposed send the electrons through the wire to the positive side of the battery? If so than why is it that in the schematic drawing the positive side sending electrons to the negative going backwards through the diode?
+Rory Hemmings In reality electricity travels from negative to positive, however it was originally though that it traveled from positive to negative. This is why the schematic symbols are drawn that way - and it still works, because you can think of it as traveling from positive to negative by losing electrons, instead of gaining one going from negative to positive.
+CodeNMore ok thankyou
In a battery...current always flows from Negative to positive ...so the resistor must be connected to cathode side only...why here it is connected after load{led}
renuka j it’s based on the convention of electron flow, which originally was developed by Benjamin Franklin. It’s easiest to think of it as a current of invisible positive charges flowing from the positive end, or like a “current” going towards the negative end.
Thanks
my favourite dialogue that you say ,,, "What in the world is something?" :p
we have a lot of electronic components but i dont know how to use them
I’m a programmer and always wanted to learn about circuits and hard stuff, I think here’s my place
I think the LEDs terminals are backwards
Yah I think you are right, the cathode should be connected to the positive terminal of the battery, not negative to negative.
But the series of videos seems to be useful even to electronic students
Woudn't that diode be off (not work) because of the polarity the diode is connected in that circuit
because the current is flowing from the negative terminal of the battery to the cathode of the diode. I heard the current has to flow from the anode to the cathode and with a Vth of atleast 0.7V
Kassim Nazeer i know I'm really late and you've probably already got the answer but if not: i think it's because engineers first believed that electricity flowed from positive to negative; 'conventional current' but when they realised it was the opposite they didnt change the schematics, hopefully this explains it to you and other viewers looking for the answer
I just like going to this playlist and clicking Next, Next, Next just to hear "What's going on everyone" lol
I agree 🤓
K, you said to try and figure out what this does, so I paused to write my guess. Since you said it's a schematic of the thing we just made in last video (battery + resistor + LED), the part where the drawing breaks at the top is the battery, the squiggly is the resistor (representing sending the electricity in a diverted path to use some of it up (kind of like the magic shoebox in networking they used to solve stock traders who built faster fiber-optic connections so they could buy stocks other people requested ahead of them, then sell them their requested stocks at a slight gouge), and the thing with arrows coming off it represent the LED casting light off it.
The white lines represent perfect wires.
Cool about how to tell if wires that cross are connected, thanks!
*Summary:*
- schematics show you a circuit in drawing form (shows the battery, resistors, LEDs, and any other components in your circuit)
- battery is shown as 4 lines. The side with the longer line is the positive terminal of the battery while the side with the shorter line is the negative terminal
- resistors are shown as zigzag squiggles (or sometimes as just a rectangle with a number of ohms written on it)
- LEDs are shown as a triangle and a line
If you make video about datasheets, I'll subscribe.
A schematic for construction or mechnical are alot more difficult for me.
I don't think it is correct. On the breadboard you connected the LED + with the Battery + and then you connected the Resistor between the LED and the Battery MInus. I believe you need to explain the real Current Circulation and the conventional Current Circulation.
I believe this can be confusing for the new guys.
Respect for the way of explaining things.
Tbh i find schematics to be awesome
Please be my science teacher 😢
I'm the 1,000'th like😁👌
