Thank you for the history lesson! Very interesting. The speed at which knowledge was gained and inventions made during later years of electrical discovery must have increased exponentially. I cannot imagine the number experiments and devices built to measure electricity. Such interesting times. I have to wonder if we truly understand the whole of electricity or even the depths of the atom. Then there is gravity. Imagine how great the discovery of gravity control would be.
Whenever I hear the discoveries of that era I can’t help but wonder, where does one draw the line between “rigorous & disciplined testing, along with keen observation and recording which leads to a repeatable result” and “complete accident fueled by obsessive frustration”. When I started learning electronics I was taught using conventional flow, which made sense to me, at a basic level but for some reason something didn’t “smell” right, at a sort of corporeal level. When I learned electron flow, for whatever reason, a light bulb went off (lol, pun intended) and suddenly everything made sense. For me, personally, electron flow makes more sense.
Wouldn't be great if Electron Flow became the standard? I understand both, but still fight with it while attempting to diagnose PCB issues. This is what happens a wrench monkey nerd tries to be smart enough to learn electronics in his 50s. Hahahaha
Electron flow makes perfect sense. It's reality. Furthermore, you must use electron flow when analyzing vacuum tubes as individual components. The problem is that the literal higher pressure is labeled negative, and the lower pressure is labeled positive; negative is greater than positive. So, the whole problem is that early scientists got the labels backward. If electron flow works for you, I have no problem. For me, I have to make an unpleasant mental twist to have a fluid flow from a lower entity to a higher entity. It's easier to forget the electrons and think of electricity as a fluid that naturally flows from a higher pressure (positive) to a lower pressure (negative). Doing that makes it easy to visualize how components and circuits work; it's just plumbing.
Can I make one request Sir? Can you please make new video about Make Before Break MBB and Break Before Make in multiplexers ICs? Please... The working, advantages etc... please 🙏🙏🙏
I will have to do some research, but from the name, I'll bet they work electronically like mechanical MBB and BBM switches. In other words, while switching from one channel to another, an MBB multiplexer will probably not break the connection to the previous channel before making the connection to the next channel; both channels will be connected for a moment. A BBM multiplexer will probably break one connection before going to the next. The reason for the difference is probably because some systems can't handle an interval of no connection during the switching process, whereas others can. This is total speculation about something I have yet to encounter. Let's see if I'm right.
He stood on the shoulders of giants. He didn't discover any new principles, but applied them in new ways. For example, the motor had already been invented, but he figured out how to make them work with AC.
Thanks for the comment. I have looked into the "Baghdad Battery" and don't believe they were batteries. As found, the jars couldn't have worked as batteries because the copper had no connection outside the jar. Also, the tar seal makes no sense for a battery. Such a seal may prevent evaporation of the electrolyte, but as the electrolyte degrades over time, the seal makes it unnecessarily difficult to replace it. The seals would also prevent the escape of gases produced during operation. Early liquid-based batteries of the modern era were unsealed open vessels. There was also no need to make the copper cylindrical. A rod of copper would work as well. In other words, if I were to make a copper-iron-vinegar battery, I would put the metals and vinegar in an open beaker. Furthermore, supposedly electroplated objects found in the area turned out to be gilded using mercury. The purpose of the vessels is unknown, but an archeologist who worked in the area for 20 years said she knows of no archeologist who believes they were batteries. Also, I think you are confusing Thomas Jefferson with Benjamin Franklin. Franklin did not discover electricity. Static electricity has been know since ancient times. Franklin's contributions were proposing an experiment to extract electricity from clouds (Dalibard beat him to the punch) and proposing that the two known types of electricity (vitreous and resinous) were actually the same thing. Alessandro Volta invented the battery.

It is a pity that college instructors do not spend time talking about the history of discoveries. This stuff is so fascinating!
Thank you very much!
Exelente información! Thank you!
Learned more about Franklin.
Volta’s battery opened a big door , as there is only so much you can do with static type electricity.

Great stuff
Now I know where "juice" came from and why "amber is the color of your energy.*
HEY!!! You totally forgot Oliver Heaviside...
A little too deep for this video.
Remake time.
Great lecture, terrible hum in the audio
I don’t have hum
Can I make one request Sir?

@Vocademy-Electronics-Tech okay eagerly awaiting for the video thanks Sir 🙏
😎💚💙👍🍺🍺🍻
What did Nicola Tesla Do?
He stood on the shoulders of giants. He didn't discover any new principles, but applied them in new ways. For example, the motor had already been invented, but he figured out how to make them work with AC.
@Vocademy-Electronics-Tech so x-rays? High frequency electricity? Neon light? Radio? Scalar energy? Not discovered by Nicola Tesla?
I think it’s fair to say that the ancient Egyptian’s created batteries long before Thomas Jefferson’s “discovery”. Batteries, i.e. electricity.
Thanks for the comment.
