Old vs new, then you get a healthy charged battery vs dry cells with low voltage. Now I didn't think this was supposed to be can you mix healthy + unhealthy batteries. That's obvious. Your 3 batt setup also generally won't power devices with a dead unit. Try powering a 24v appliance with 12v. Then I have never seen or heard of a battery charge to reverse polarity. But I just revived a 2001 dry cell sla under 1v with a bit of batter water and a week of charging. It's quite concerning what wisdom the poor commenters and viewers received from false information

Thanks 🙏👍💯😊

Thanks for the through and well thought video. Can you explain in detail how the transistor will not exceed 50mA, isn't Ie dependent on Ib ?

Dejavu of 33:41 at 40:33 :) amazing job btw.

👍👍👍👍👍👍

Interesting.

I wish I could upvote the video everyday

Pl correct capacitive reactance variation with frequency.

Thank you for the video. Very helpful. I am new to ham and am looking to build a power supply as my first project

An excellent demonstration, thank you.

Ive been busting my brain trying to figure out transistors as amps, turns out most of my issues were using a circut like the one in the first half of this video. Not a single other person has told me its almost impossible to calculate predictable repeatable results using the first circut shown here.. Best explatation of common emitter ive watched!

But if I go into the hole's frame of reference the electrons are the only ones moving and the net charge is negative. This doesnt solve anything???

Great video. Just as an aside it shows not to be in water when working with electricity.

The way I see it is that electrons and holes are not the same. Electrons can be injected into the wire or forced out of the wire by the external applied voltage. To a stationary observer, even though there is length contraction for the moving electrons and hence they should have higher density than the stationary holes, the externally applied voltage pushes enough of the electrons out of the wire to make the wire electrically neutral. For the moving cat on the other hand, the moving holes are fixed physical attributes of the wire which can not be added to or removed from by the external circuit.

Very good explanation 🌅🌅

excellent👍🌹

You the best in my books 🙏🏽👏🏽

At 8.11 also i believe that the mistake is repeated. Where the n fet is described as p fet. I also had to confirm against other resources. If the chanel is n chanel then i belive we have an n mosfet.otherwise all very very good. I have been following the channel for 3 months now and i have made so much improvements. Thanks so much for the free lessons.keep it coming

in my journey of electronics I learn from comparing components what they do and what will gonna happens . and I'm thankful teaching electronics fundamentals online so opportunity to learn online it's blessing for me and everyone to learn electronics for different purposes they love

Was it was really clear, I appreciate your explanation very much. Thank you. p.s Actually I am in master studying in engineer of electronics

You’re an amazing teacher 👑

incredible video !

Thank you for an excelent explanation on how does the circuit work

your channel is very underated, best explanations on youtube

excellent explanation! other video's were not clear but this way of explanating works better for me

❤❤❤❤❤

❤❤❤

Bad Prof !! but I forgive you as your videos help me stacks !.....cheers.

Your style of explanation is more than wonderful. I support this channel. Thank you for your efforts, sir👍🌹

Finally a good video that explains a circuit, and what happens when you put certain devices into it and what effects it has! I think most of us know the single devices and how they work, but only if they are alone, not if they are matched together!

Why the blue shirt? Do you only own one shirt? LOL. Thanks for the videos nonetheless.

excellent video and very understandable. thank you sir!!

Sir, Thanks a lot. For this great lecture. Keep posting such greatful lecture. God bless you.

Is this how 0-10v dimmers work?

I’m getting into electronics, and I gotta say, you’re a legend

.5v/80ma=6.25ohms on my calculator.

Very great sir

Hi sir can u guide how to change circuit to drive bigger motor in small drones..

So happy i came across your videos. I wish i had you as a teacher 20 years ago. Thank you !

Thank you very much❤

Simply great No words to express

Best electronics teacher of all time

Space itself doesn’t and spacetime does have a unique FoR for a traveling light source. Special Relativity means the source produces photons with speed of causality no faster no slower . We are neither dealing with photons nor special relativity when we measure an arbitrary drift speed in a wire. Read again if necessary. Veratasium Derek has hijacked Special Relativity along a dubious Feynman referral. Recall, charge though the wire does have a unique frame and it’s protons certainly dont move relative to the wire FoR. Recall conducting band electrons in surface of metals may be described as a unique FoR equivalent to an arbitrary potential drift velocity relative to the atomic structure of the non neutral wire. Hence what might be relative in spacetime falls on its head wrt presuming a moving FoR of protons relative to the wire lattices. No. The length contraction is ONLY relevant to relativistic velocities where time dilation offsets. No this is 10s mm/sec velocity not 3x 10^8mps . Sorry… sorry the protons are not squished the way conduction band electrons may be and the drift velocity is ten orders of magnitude too slow for the speed of causality (light-vacc) to be relevant. The problem here is of your own making trying to fit special relativity in for both + and -. Am I wrong…? Happy to be corrected. But make it watertight… cause i might plunge in otherwise

Excellent, congratulations!
