Inductors and Capacitors In-Depth - Exactly The Same Only Completely Different - Simply Put

[@robinbrowne5419]

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 :-)

Inductors are like a flywheel for current

To learn electronics without learning math is the attempt of a fool. You are a VERY good teacher of these concepts. I'm commenting here 5 years after this video came out and I just discovered this channel.

[@sweetjetsband]

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!

[@gustavoassad2250]

when you used the fact that inductors don't use energy to oppose the electromagnetic force, made everything very clear. thank you very much sir!

[@LuukP20]

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.

[@ebarbie5016]

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.

[@sneakyboii732]

hello everyone, i have a way to understand inductor reactance easily and intuitively(my take at least)! first, assume the AC case, where we measure signals and such. The inductor is replaced by its reactance 2*pi*f*L. The voltage across the inductor IS the backwards EMF. Now i know that the direction of the voltage drop is in the same one as the polarity of the signal, but since the EMF subtracts from the total voltage drop, its literally the same. Now, assume we have a signal passing through our inductor, with a frequency. We'll analyze in both high frequency and low frequency cases. Imagine the signal as being an infinite sum of dirac impulses (math concept i learnt in signal processing, its basically a square pulse with an infinitesmally small width and a height of 1, the height could be any unit, and in our case it's volts, and on the x axis we have time in seconds). For the duration of the dirac delta, the EMF decreases, because in that time the current is constant, and the EMF decreases gradually. As the frequency increases, the width of the dirac impulse decreases because the voltage changes more rapidly, not giving enough time for the EMF to decrease(in either direction that the signal swings), and thus the voltage across the inductor increases more and more (because the EMF decreases less and less) and at very high frequencies the voltage of the signal will be dropped entirely on the inductor, or the EMF will decrease extremely little after each change in voltage. In the low frequency case, the voltage drop across the inductor decreases because the impulses have a longer duration, in which the current is stable and the EMF has more time to decrease until the next impulse, making the voltage drop at the end of each impulse and right before we move onto the next, smaller. Anyways, that's my take at least. Simply Put, thanks so much for the video, without it I might not have figured out this stuff! I'll try figure out the capacitor next and I'll post it here too! If I am wrong in any way, please, correct me. And if you have any questions, please ask!

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 ...

[@waterfuel]

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.

[@wm437]

Excellent teacher. Thank you for taking of your time to explain this to us.👍🏼

[@tonybp]

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.

[@Rico702Vegas]

2 minutes into the vid and I'm subscribed! Nice to hear an American voice (not dot heads who can't pronounce capacitor) whom possess not only a sharp mind, but the ability to teach this knowledge intuitively and in a way that most people will understand it. Thank you bro!

[@g.d.8065]

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).

@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.

[@raymondgarafano8604]

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.

The thoery of relativity connects the electric and magnetic field , actually magnetic field is also a moving electron but you are observing it in a different frame of refrence[watch varistasium video on it] , I liked your wreking ball analogy , also i like to think capacitor is like a mini water tank , if you increase the freuency of water going in and out from the same pipe ,then tank doesnt have time to fill ,it remains the same just like capacitor , and the wrecking ball is just the opposite , despite both wreking ball and mini water tank work on completely different concept , we can observe that both work are like reciprocal of each other , so thanks for the clarity on inductor ,I wish my school had someone like you to solve my doubts ,some one so practical and creative ,who can basically breakdown any problem into simple real life examples , Again thanks for the video ,It helped me a lot.🙏🙏

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.

[@chrischadwick7941]

A wise man once told me I can harvest emf with a inductor and that'll feed a capacitor and with a diode I can send that charge to a cell to store the energy. Can you simplify this as you have with your hi pass low pass understanding. We live in a world with a constant 7hrz and the right shape inductor can be harmonically tuned to this?
