No you are not the idiot. You are the only smart person making electronics videos. In every book, video, song, about electronics they explain it like they are talking to someone who already knows what they are talking about which helps no one. They also forget that they didn´t understand any of the learning materials back when they were learning it either because it was shit so the cycle continues. Great explanation. Keep it going. There are already close to 1500 people who came here because they needed help.
Your videos are great. The split power supply and transistors didn't make sense but they do now! I'm learning some of this theory to build simple analog synths.
I just need to make a usb cable that has two separate 5v inputs , whose wattage may vary (2 separate solar panels with only usb a female 5-5.3 v /2.4amp outs) into one lead. I have read about placing resisstors before and after the joint but which ones , or if you know of an easier solution, like a premade board that combines two inputs on amazon or something that would be great. Also, your reference to glossing over details is a good reminder but it is a " double edged sword" in a manner of speaking. But , simply explaining precepts or foundational concepts that are often taken for granted I think can be one positive take away that is anti-entropic, ie, knowledge is power. I am applying this to life , spirirual, understanding , because, though what you said apoears to make sense, it is still way above my head. But, kudos for a good video.
From this biasing I understand the Q point is still in the middle of active region of transistor .. this mean that the output of the ac signal with have dc component and we need a capacitor to block it... if that's true then why in opamp(which uses differential amplifier) the output ac signal has no dc value ?
okay, for about 2 or 3 months I was looking for a way to "turn on and off a dc battery" to simulate AC because I wanted it to go through a transformer without buying a boost converter or inverter because that's too much extra crap considering you can turn ac to dc wi8th just a SCR, anyway I found the amazing 555 timer and was so happy because it could produce a sine wave with dc so i set up and connected a 110 to 9v transformer to it (backwards) and managed to get 84 V AC but I wasn't able to get negative voltage and someone suggested I use an op amp and I'm having so much trouble with it but at the beginning I thought I could do this with mainly a transistor (like the SCR) and well I find this video. I wish I found this sooner.
I never really got this either and messed with thsi stuff for years. Auditing a linear lectronics class at the college I work at, perhaps one day i'll teach the class. I saw it on the board It then clicked I was like ground is whatever you say it is. Another way I see it is if you understand how 120/240V AC works on a normal single phase power service same thing. They are oposite 180 degrees, so center is ground reference, then you get 120 on each side, but one may be say + the other is -120V, so then bewtwen those you get 120+120=240. Same goes for 3 phase if you have a neutral it is just whatever is ground referenced.
Will this work for doing rail voltages on op amps? I tried it but doesn't seem like I can get it to saturate to the rail no matter how high I put the voltage input.
Thank you for presenting this very interesting topic. But graphic diagrams should be better understood than using your hand gestures. Diagrams and graphic videos can make understanding easier
I thought you said you were going to simplify this concept of negative voltage. You didn't help me because I'm one of those that this doesn't make sense to me intuitively or otherwise even though i fully understand the use of negative numbers in mathematics. But, how do you have a negative voltage?
At this Time I understand nothing. It´s Electronic understanding next level vor me. And Nevertheless I can take a lot with me / learn a lot I´m from Germany and can only understand a few words. Thanks for your great Videos
I found your video because when I built a rectifier putting the cap negative side to the negative rail (not earth) was both logical and confusing at the same time. I thought about it a lot and thought - but its a voltage difference ... why does it flow backwards ... well yeah, its negative so backwards - but i just thought the cap would explode when I turned it on anyway. THe fact that there are 2 caps across the 2 rails and ground in the same polarity makes sense - neg to positive ... its just weird. Just one comment - the way you edit it all to sound nice as audio - that's just fucked for me to hear and view - constant discontinuity. I don't enjoy it - and i've produced and edited a SHITTON of live, edited post, vlogs ... and sure they have edits but not one per sentence and its not done because like me - it fucks with many peoples heads. So ... like you use 2 powersupplies for a reason, you don't edit like you have ... for a reason. If you prefer it - no worries its your content. You also don't really seem to leave pauses ... that are necessary. Its just relentless speech ... because of your editing.

Your opening statement applies universally, regardless of topic. It should hang in every classroom. Bravo.
I like the way you explained this, great job.
I had trouble getting may head around it , then the penny dropped, thank you.
8:58 ...and welcome to entropy...GOOD ONE lol !! well explaint as usual !
I think zero base signal turn this configuration as common base configuration.
Thank you. I have been trying to find this level of detail on this subject for months.
Thanks!! you just saved my tomorrows exam!
Great explanation and example. Please keep making videos!
Your videos are great. The split power supply and transistors didn't make sense but they do now! I'm learning some of this theory to build simple analog synths.
Yeah, takes a bit to get your head around it. We'll explained and also good demonstration on the breadboard 👍

yeah this guy is awesome

don't negative voltages cause things to blow up?
Great explanation thanks!
Awesome explanation. Thank you. I just subscribed.

I don't understand positive voltage, electron's are negative, can you explain please
If you are working with op amps and you only have one power source. How can you split that to positive and negative power?
Thank you for presenting this very interesting topic. But graphic diagrams should be better understood than using your hand gestures. Diagrams and graphic videos can make understanding easier
Oh i hooe you haven't disappeared I like your videos,
I thought you said you were going to simplify this concept of negative voltage. You didn't help me because I'm one of those that this doesn't make sense to me intuitively or otherwise even though i fully understand the use of negative numbers in mathematics. But, how do you have a negative voltage?
as long as you use only conventional or only electron flow when talking (which you are doing)
At this Time I understand nothing. It´s Electronic understanding next level vor me. And Nevertheless I can take a lot with me / learn a lot I´m from Germany and can only understand a few words. Thanks for your great Videos
After watching quite a few of your videos, I can say one thing with absolute certainty, you are definitely not dumb. Quite the opposite in fact.
I found your video because when I built a rectifier putting the cap negative side to the negative rail (not earth) was both logical and confusing at the same time. I thought about it a lot and thought - but its a voltage difference ... why does it flow backwards ... well yeah, its negative so backwards - but i just thought the cap would explode when I turned it on anyway.
