Yup. You are right that they are exactly the same but completely different. When I was in college I understood capacitors but not inductors, so I asked the instructor about it. He said "Well. What do you think a capacitor is?" So I said "A rechargeable voltage source". So he said "Then an inductor is a rechargeable current source". It all made sense after that. (Except for calculus with complex numbers. Lol.) Cheers from Canada :-)
Love the straight forward explanations in your videos. Something about the way you explain them makes it seem like you're actually just trying to convey to me a concept over beers at the pub rather than in some heady, academic way. You know your stuff and you make it really interesting and easy to grasp! Thanks and keep it up!
@@GalenMatson I too have only positive and no negative views to charge this way of teaching with, and that’s saying a lot since my capacitance for learning is well under spec
Lent's law has nothing to do with back EMF, but rather it's related to forward/front EMF. Trying to stop or decrease the current (or magnetic field) of an inductor will cause forward/front EMF that will make sure the current (magnetic field) remains continues. back EMF is actually a result of Farady's law.
This was a great video. I've been watching lots of presentations about decoupling capacitors and seeing the reactance by frequency graphs and so on but this video gives me a much more intuitive model to digest. Many thanks!
Symbol of inductance is L honoring physicist Heinrich Lenz. Your explanation about the magnetic field opossing changes in current... that is Lenz's law. :-)
I do not know why you do not have a Zillion subscribers. Your vid's are fantastic. Concise and so on topic. Thank you............you have become my goto in this fantastic field of engineering. Dave from "Downunder"
I like your humor , and your explainations are detailed enough for any one to get a general idea on the function of both of these "sometimes" confusing components ... Thank you ...
Excellent video. And you're so right, I definitely had an easier time understanding capacitors as opposed to inductors, it was a pain for me to grasp inductors with the counter EMF and expanding and contracting magnetic fields, and polarity changes and this and that... ugh. Anyway, love your videos, this was a great refresher for me.
I was looking at a buck converter circuit and trying to figure out the role of the inductor and the capacitor right after the switch, but I found myself unable to tell what exactly the difference in function was of the inductor and a capacitor. So I looked for a video explaining the two. I do not understand 100% of what you just explained but things make so much more sense now. I am saving this and probably going to rewatch it over and over again, having it make more sense everytime I watch it. Very good video. Thank you for making it and taking the time to teach other people your wisdom.
@Simply Put. Just joined your excellent channel. Being able to explain this in laymen's terms like you do it is just pure genius. Most academics cannot teach but you certainly can. I am sure many EE grads do not have the depth of understanding that you have too. By the way Eugene Khutoryansky (a physics prof.) has a video that explains capacitors really well. Well worth a watch if you have not seen it yet. Basically as the electrons build up on one of the plates they repel the electrons on the opposite the plate thereby creating a current flow. Anyway, love your insights. Thank you.
wow. this is an excellent video. Great work! I like your humour and examples that you use to explain complex things. your videos motivate me to learn more.. you are patient enough to edit videos!
Thanks for your amazing video. Just imagine voltage applied immediately while current needs time to flow. I understand it this way since college days 😅
@@simplyput2796 One of my instructors would discribe the inner workings of some chips as science because explaining how they worked was a little to hard to understand for some people.
Wow great job explaining ive tried to understand these things more than once but your video just helped me mind grasp the theory so much better. Thanks . this is the second video on this channel ive seen and. Theyre both great
i just found your channel and this is the first video of yours I've watched, but I lost my fuckin shit when you turned your head to reveal your modded out headphones lol, I want a set, but I am not very skilled at audiophile level stuff like that. serious note though, You're a good teacher, I've had a hard time wrapping my bean around inductors, this made it click, thankyou!
Such a video didn't really existed until now and a lot of people working with electronics don't know these. Well done! I just wish if you said something about saturation.
Awesome! That was really interesting and also made me laugh. I'm going to make a battery power supply for a tube amp and researching the topic. To understand wtf I'm doing and also get a clean DC.
One way to think of capacitors in series (conceptually) is to add up the gaps within each one. Capacitance is inversely proportional to distance, therefore distance is inversely proportional to capacitance, so you add up the inverses of each capacitor to get the sum of the distances, and then take the inverse of the result to get the total capacitance. (Capacitance is also directly proportional to plate surface area, but it works out anyway. You could probably think of the surface area simply being distributed across the plates, but I'm not sure). While I did come up with the intuition for the formula myself, the actual conceptualization of adding distances is taken from one of Eugene Khutoryansky's videos (which I highly recommend). Parallel inductors can be thought of as being akin to resistors with values that decrease over time. Therefore, the formula for resistors in parallel also works in this context (adding up the currents flowing through each and then taking the inverse to get the effective inductance. Two identical inductors in parallel have the same current as a single inductor with half the inductance).
I saw this inductor current on the O'scope when I built a telegraph. Once I would hit the key, and release the Code Key, there would be a momentary Strong Spike "A Spark ' produced by the coil in the ' Clapper' I had to install a Diode to prevent burning of the points in the code key from this spike. It's a nice basic experiment with Coils and Back Current ...
very well put, how u compare physics is great, the wrecking ball hangs str8 down. pushed forward with a truck and held, the power that the truck needed to push the ball will be stored in the ball, when the ball is allowed to swing back, it will have a lot of inertia, same with magnetic field around primary of ignition coil, points open and the flux bilt up now collapses back into primary coil, that is why a condenser is across the points making a tank circuit, absorbing the back volts an keeping the points from burning out.
Hello Simply put, I'vebeen messing with primary of microwave xformer modified to be an electro-magnet, there is a real bit of an arc when disconnected from a storage battery, is a condenser across the points of ignition coil a tank circuit? Very interesting, as I get it, less current thru and inductance, say field of traction motor, less current thru it, lass back voltage.
I think i got it, you are good, excellent explanationS; it sounds like you know more beyond that too, maybe A LOT more? And i have another question; your hair and beard, are they in series or in parallel,difficult to tell from here.. lol, thanks,man
Back in 2008 , there was a circuit I read about that added 100v to the existing circuit that was going forward as pulse on/off 40V DC about 6amps. There was no capacitor. The part added was a sealed 60cycles AC relay in vacuum with dual inductors 1.6Millihenry each, of .6ohm. Diode in front of 1st coil L in series with internal diode in between L coils then that 2nd coil L in series with another output diode. Did this arrangement just happen to be lucky and obtain the needed extra 100volts forward? Back EMF forced forward as flyback voltage put to use? I have many inductors to practice with and I need to get just voltage to superimpose on to circuit line. 100v or a miniature autotransformer.
