Thank you for this video. Could you also delve further into the voltage rating aspect of the capacitor and will it affect the charging and discharging of the capacitor? For example if voltage source is 30v but cap voltage rating is 63v, will it still charge at the same speed? In this case will it be 63.2% of source voltage ie 30v or the voltage rating of the cap which is 63v
What I don't understand is, if electrons move, they contract. That means, in my head, from the perspective of the moving electron, it looks normal but the whole world gets wider. But in these videos, they claim the opposite, that the things around you look shorter too and not wider. I'm confused.
Very informative videos and probably the most accessible explanations I ever had. This is not an easy topic but the videos make it more understandable. Thank you very much! Many thanks!
Hello sir, i have a question and that confuses me a lot, as we know the op amp does what ever it takes to make both the inputs equal. But then it seems weird because output of an op amp is gain×( V+ - V-) and since the op amp made the inputs equal it should give zero volts output since now both inputs are at same voltage if we observe this in other configurations of op amp as well the voltage follower.
No sir, you are wrong. Holes don't move, they are protons and protons isn't effected by special relativity neither. Derek explained what he must explain in this video, maybe you didn't hear. He said "in my frame of reference cable is neutral". So moving electrons has to be same amount as the protons even after starting moving and getting constracted as SR says. So counting them after saying "the cable is neutral" doesn't make sense.
You proved that when there is a good tutor and a thirsty leaner, then a teacher need just a pen and white paper or white board. Both does not need fancy tablets and fancy software and crap. simple, a pen, Knowledge, way to deliver knowledge and a white board.
Sir, huge respect for stressing how oscilloscope isolation from mains is not a good idea. Nobody else I've watched has explained it that way. Now I have to learn how to setup two channels on my oscilloscope to read potential difference. People can certainly get a false sense of safety when using isolation transformers. Thank you very much ❤
Dedicated and detailed lecture. Thanks professor. LGM is also IGM--- invisible Green man. Was Wondering what's LGM model.. Never heard of it... Wish you all the health and happiness for the wonderful contribution to young Electronics engineering community
The opposing emf produced by an inductor is a characteristic of the non-Coulomb electric field that is proportional to the rate of change in current causing a changing magnetic field. And that is Faraday's Law. The current is a result of the combination of an opposing Coulomb electric field and the applied field which is changing the current. The opposing Coulomb field is a result of polarization of the inductor by the non-Coulomb electric field. So, the current is a consequence of the resultant field of the applied field and the Coulomb electric field in the inductance coil and is determined using the governing relation in conductors J = σE_net. It is not possible in this post to discuss in more detail the formation of the Coulomb field when the current in an inductor is changed. Before learning Faraday's Law and its application to the operation of inductors, it will be instructive to understand Current, the conduction process and Voltage at the fundamental level as in the following two videos: i. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-TTtt28b1dYo.html and ii. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-8BQM_xw2Rfo.html The last frame References in video #1 lists textbooks 3 and 4 which discusses topics on inductance and inductors in more detail using a unified approach and provides an intuitive understanding of inductive reactance. It also describes with sequential diagrams how an inductor develops the induced emf. Textbook 4 techsarworld.com/product-detail/fundamentals-of-electric-theory-and-circuits-559 shows how the current lags the voltage across the inductor by 90 degrees for sinusoidal input voltages using sequential diagrams.

I was forced to abandon my former work due to a forklift accident in 2008. My doctor tole me to "find a desk job". Since then, I was able to take a hobby of mine (building effects pedals for electric guitar) & build it into a successful business. I didn't have the money to go back to school to formally study electrical engineering, but was able to purchase my first computer in 2009. Prior to that I had to go to the library or use a friend's computer to print out schematics & order parts. Having constant access to the internet enabled me to learn electronics at an exponential rate & start my own business (Acid Fuzz). Channels like yours which provide free EE courses & informational videos have expanded my knowledge immensely, and helped me in many ways along the years. Thank you for all you do! Your presentation style is excellent & ~second to none on RU-vid.
Excellent video and the best teacher I have come across, here in Australia they use nanofarards now, I am old I learnt it in uF, so a .47uF is now 470nF ...most capacitors are labeled that way now..Things change..
