Great work, Leo. Self-taught in electronics, I was put off by the math. 27 years later, I'm teaching my students with a similar intuitive approach first and will definitely point them toward your video series. You're a great explainer. Respect and thanks from Waterloo, Ontario Canada.
I love the analogies and the simplicity you bring to these concepts. I am currently learning electronics from University and I am here to say that I would have caught on so much faster if the fundamentals were explained this way. I remember when I was first learning about voltage and current from school having such a difficult time understanding what was actually going on. If I watched this during my first semester I would have saved myself tons of headache for my future classes.
Simply explained. For many students, this is often a difficult subject to grasp. The relationship between voltage and current is not easy to explain, but you managed it expertly. We are hoping that you will continue this course into semiconductors and beyond.
I just found your youtube channel and am totally blow away by your knowledge and teaching skills. I have a Masters Degree in Science of Teaching and can say you have mad skills. I also watched one of your other videos where you say you are a high school drop out. Yet I see a person with a comprehension of electronics that some formal educated people do not have. I can only imagine what knowledge you would have and the contributions you could make if you had a PhD in electrical Engineering. You also would have made a top notch teacher for high school or an adjunct professor at a University. I especially liked the part where you said you learned the hard way by keeping your nose to the grind stone and not quitting. My education is in the sciences, chemistry, biology and mechanical engineering. I am now 66 years old and retired and have been learning electronics over the last three years just as you did by teaching myself, trial and error, reading and doing and keeping my nose to the grind stone. I now have gotten to the level where I have a small shop in my basement and repair radio receivers, stereos and other home electronic devices as a hobby. Thank you for your efforts to teach and I subscribed and will be watching all of your content.
I have never been one who intuitively understood mathematics, it has always been very foreign to me. So, years ago, I struggled greatly with it. Then one day while in a used book store I found a copy of Mathematics For Electronics, by Clyde N. Herrick. This author assumes that the reader does not have any previous training in math and he takes you one step at a time through it. I have learned a great deal from this book and it is an invaluable resource for me. He puts all those authors out there writing math books to shame, as the vast majority of them assume all you are wanting is a refresher course. I would suggest to everyone interested in learning electronics to do everything they can to locate and buy a copy of this book. They won't regret it.
Great work again Leo. I always wonted to learn electronics sign up to many online courses just to be lost on mathematics. I hope you will continue this series . Thank you for dedicating your valuable time to make this video.
Being a student with major in electronics i can say you have quiet an extraordinary way of explaining concepts. Well Thank you and keep the good work going.
I'm 72 and own "FineArtLight" a n art lighting business. Recently my supplier of Halogen light bulbs quit importing to the US. I was forced to learn about LEDs that use 700 ma and 3.3 volts. Luckily I have a LED consultant who developed a 12 volt contols board to deliver the 700 ma at the 3.3 volts required. We have the boards currently being built in China but due to the tarriffs we have decided to build them here in the US. My LED consultant has a pick and place machine for the first 1000 units but does not want to make the next 10-20 thousand units. I need to learn electronics and understand what he has created in case anything happens to him. I might have to buy a pick and place machine to continue production. Thank you for your wonderful class.
Thank you very much! My whole life.. Well the last 20y at least, I wished I'd get this.. maybe this course will be my new chance of getting a bit of an understanding of this amazing technology that is in everything I love and need. Thank you!
This is so kool!!! LoL when I first heard you I thought “Oh No” what is this guy selling. Then I said to myself, calm down and listen to what he says on a lesson. I love the concept you are using to get us started. I’m 75 and retired, I had my own business for almost 60yrs mostly creating things for people on furniture or in their homes plus add some music in along the way. So now I decided I’m not throwing one more tool, appliance or gadget away that looks brand new unless I try and fix it. I’ve purchased the basic tools and already fixed a few things😊 Next phase please, lol, electronics. Is there someway we can support you here? Thank you very much!!!
I’m 52, and have never been exposed to electronics. But I’m very interested in learning! I’m horrible at math and one other video started right into it and I freaked out and left. Since then I’ve bought a kids snap circuit kit to hopefully help me understand but I’m finding myself upset that they show you project but not offer the whys in how it works. I found your videos and I hope that I can catch on and not get overwhelmed by the math of it. Looking forward to the next video!
Thanks for the effort you've put in making this video. I specially like the way you explain abstract ideas using simple analogies. Hope this video gets watched by as many people as possible. Cheers,
Eureka! What a great video to learn electronics. Your visual aids and diagrams along with your clear cut explanations made for an easy to understand lesson.
Great video Leo, absolutely loved your straightforward and intuitive approach to explaining the fundamentals and can't wait for the rest of the series!
I can definitely relate. Too many instructional materials focus on the math instead of concepts. Instead of explaining relationships using real world analogies, many of them jump right into equations and graphs. It's not so much that the math is difficult, often it's just basic algebra. What makes makes it difficult and discouraging is seeing the relationships in the math. Electricity is analogous to hydraulics and pneumatics, yet both are far more intuitive because we all have observed their behaviors and properties in the real world.
I’ve watched many videos, including those on Udemy. You are the first person I discovered who could clearly describe the electromotive force to me. I will watch your series. I love electronics and can solder and replace capacitors but I don’t enough of the basics and how to troubleshoot faulty device using a multimeter. I should probably by a book as well. Thank you for putting this video and hopefully others. I subscribed.
I like your approach. I was never great at math. My Father could do high math like a musician sight reads music. His brother was a human spreadsheet- he could add long strings of figures in his head. Some how it missed me. The conceptual approach I think works quite well.
I love this video . The simple and clear way you present the principles is fantastic . I am looking forward to this series . You have a love for plants like my mom did . When I was growing up I would say I heard jungle drums last night . She had over 300 plants in the house . She had a green thumb . Thanks for sharing , stay safe . Terry
Leo, Happy New Year mate, loving the work you are doing and the end result, will be mind blowing, I’ll be sure to watch the whole series, keep up the amazing job. 🤙🏼🇦🇺
In solid copper (and other metals), the electrons are actually unbound. More precisely, the electrons are strongly bound to the extended solid, but they are NOT bound to any particular atom. This is why they are great electrical conductors, why they are great thermal conductors, why they bend easily without breaking, why their heat capacity has no aT term, etc. Each conduction electron is 'delocalized;' each wave function occupies the entire object. There is no way to identify any particular electron because they are all exactly the same. To predict what we actually observe, it is necessary to expect that they spontaneously exchange states in pairs at short, random time intervals. The balls' friction only interacts at the surface of the tube; however, resistance occurs throughout the object's volume. Each electron collects kinetic energy (velocity) from the applied electric field and interactions between the electrons and the 'stationary' atom cores causes these cores' shaking to increase; "phonons" remove energy packets from the electrons' movement and deliver it to the atoms.
I have a PhD in science and have been working as an engineer for multiple years and I can say your lecture on this topic is excellent. Thank you for sharing your knowledge with us. By the way, I love the random appearance of shirtless guys at @4:18.
I really really really want to become a small electronics technician but i just don't know how to go about it and everything in the video makes me want to do it even more if you have any idea where to start please let me know this is something i want to do for the rest of my life and i loved what you taught me in the video i appreciate all the info. Thank you!
Subbed!! You're what I've been looking for to help teach me this vast world of electronics. Thank you for taking the time to help us in our hunt for knowledge!
Electronic components (silicon, germanium) schematic diagrams use conventional current for the arrows (P to N direction) seen on all of the accepted/standard symbols. It's far easier to explain the diagram with the conventional current as Leo points out. I am an older electronics tech who has worked on complete avionics systems with both transistors and valves across comms and navigation devices.
In copper wire, there are free electrons that flow randomly, from atom to atom. Only when an external voltage source is applied, do we get the flow of electrons, which we call current!
I understand your aims; but I'm not really a big fan of the triangle for remembering formulae. I have had so many students misremember the triangles they were taught at school, when a little bit of simple algebra is all that is required. Other than my pet peeve, you are doing a great job - looking forward to seeing more!
Point is somebody called negative electron negative is because that electron is full of electron for pretrculy material, so there is no movement inside of atom. When atom which has les atoms (called positive) is added near to atom with full of electrons positive atom will pull- attract electron of negative- full charged atom. That is how to explay that. Not going around and newer really explay to people how that really works !
I'm 16 and picking electronic as a strand, i dont know a single thing bout it but it got me excited tho i would like to learn more about electronics even though i'm dumb "my parents forced me" ¤_¤
Great idea to build knowledge in a layered approach with the clarity you always convey! Wish I had access to such a series when I was starting out. Just one point - in the battery cutaway diagram at 3:55 aren't the cathode and anode incorrectly labelled?
it wasnt ben franklins fault. who makes the fundamental unit of any system a negative. physicist already figured out how to deal with it properly by using the "electron volt" unit which is positive
What are the circles that show up at 0:30 ? It looks like circular farming fields but I doubt that's what they are. Is it 3D beamforming with speakers/microphones or some actual circular antennas?
I'm 60. My bro gave me a drone kit for xmas last year and I have been doing some soldering etc. It's interesting to learn. What if you have 2 resistors in a circuit? Do you add that resistance together? I'm totally noob..
26 years old, starting my electronics journey and I can already tell you're a great teacher. please keep this series going
50y old....continuing where i stopped in elementary school. 🤓
@@ItsGoodToBeHaterI’m 66 and now have all the time to learn this subject which I always had an interest in. You’re never too old to learn😊

Thanks Leo I'm looking forward to following you're lessons.
Excellent video, possibly the best one on the topic! Though I know this stuff for ages, it was a true pleasure to listen to you, Leo!
First off, Great Shirts! Secondly, lessons seem really accessible, and I can't wait to move on.
Thank you, Leo! I look forward to the rest of the series.
Really nice, even as someone who already knows about it, I never really use it so a refresher is always appreciated.
This is explained so explicitly and well, thank you for your work
I really really really want to become a small electronics technician but i just don't know how to go about it and everything in the video makes me want to do it even more if you have any idea where to start please let me know this is something i want to do for the rest of my life and i loved what you taught me in the video i appreciate all the info.

More people would go into electronics if it was taught this way.
Really good. Thanks.
Excellent video, Leo. Please keep them coming. Thank you very much!
Very intuitive and easy to understand in laymans terms. 👍
You're an excellent teacher, bro! I love the simplicity of your explanations! Keep up the good work! One more subscriber here!
Subbed!! You're what I've been looking for to help teach me this vast world of electronics. Thank you for taking the time to help us in our hunt for knowledge!
Bravo! Love your teaching plan and method. Wish you every success.
Much obliged.
Looking forward to the rest! Great style.
Great video, I'm excited to see the next few lessons, I just graduated high school, and I wish I had learned more about electronics sooner. Thank you!
Looking forward to this series

Very interesting. Im retired and trying to learn some electronics but like others put off by the maths.
I like the physical analogous of wire.
This is Wonderful! I AM your target audience and I am so grateful for your work... Thank you.
Yes mate love the way this is going, looking forward to the next episodes 👍
Excellent! Crystal Clear! LUCID!
Man i just found your videos and there were really helpful. Keep it up, it looks like you have a ton more of experience than me.
Great to see you back Leo!
I ll stay tune for sure abd thank à lot for ur vid
This is awesome! I’ve always wanted to learn electronics but there is so much overwhelming information
Another great video again wow very educational 👍 🙏
In copper wire, there are free electrons that flow randomly, from atom to atom. Only when an external voltage source is applied, do we get the flow of electrons, which we call current!
Please 🙏 continue this series please
this is very informational
Wish I found your channel sooner…. Subscribed …thanks Leo
Appreciate you Leo!
Great illustrations. Keep it up!
Yahoo! Thank you for this.
You make beautiful tutorials!! Thank you so much !
Amazing effort, keep the good work! Thank you, Leo!
Great video thanks i will definitely watch the rest of the series 👍😁
Thank you :) Great job
YEEEAAASSSS! MORE EDUCATION!
Just whay I needed !!
Please keep these coming.
This is great! Definitely looking forward to more, thanks :)
