You missed the point... Why/how are they used? Why did you repeat yourself so much, then leave the installation basis out entirely?
ОтветитьWhen conventional current flows through an inductor, a magnetic field is produced. This magnetic field, also being part of the inductor produces a current that is flowing in the opposite polarity. Phase shifting occurs that delays the conventional current from being in phase with the voltage.
Power Factor is a measurement to read this phenomenon and Power Factor correction capacitors are used to keep the current and voltage relationships true. Large AC motors are prime candidates for poor Power Factor.
What about transformer?
ОтветитьI really need a usecase to understand it. So why would i create circuit like this?
ОтветитьCan you do a video on guitar amps :)
ОтветитьIs a capacitor the same thing but with an electric field instead of a magnetic field?
ОтветитьIs it possible to give Vedios on DTR faults and effects pls
Ответитьwhat if we sort the inductor in series in this circuit?
ОтветитьAll your vague comments about how an inductor works has no impact on teaching the student how the inductor works. That's why no-one knows anything and will learn nothing. You haven't' mentioned WHY the inductor eventually passes a high current and appears like a piece of wire.
I don't like your introduction of electron flow when talking about inductors because all the left-hand and right-hand rules apply to conventional current.
I don't like the switch in the negative line because you should use the 0v rail as the "footing" to all your voltages.
I learnt nothing and have been teaching the subject for 50 years. You completely missed the point that the inductor produces a reverse voltage to the load when the switch is opened and if you had 2 LEDs as the load, connected in opposite directions, the red LED will flash when power is applied and the green LED will flash when the switch is opened. You can also show the collapsing magnetic field produces a voltage higher than the supply by using a low voltage and 2 LEDs in series to show the LEDs could not be activated with a 3v supply, but magically flash when the switch is opened. That's what REAL teaching involves.
good example on how a shaded pole motor works
ОтветитьThanks
ОтветитьI don’t encourage anyone to learn electronics using fluid flow analogy; it may appear helpful at the first sight, but will lead to many fundamental misconceptions!
ОтветитьExcellent.
ОтветитьI see these on mini splits. Was curious what they do
ОтветитьThank you🙏
ОтветитьGreat video! Looking forward to why one would want the bulb (load) to turn off when the switch is turned on... Thanks!
ОтветитьWelp, now I know.
ОтветитьIt probably would help to mention the practical part of the theory where the inductor tries to maintain the peak of the alternators (power supply} voltage even when it drops to 0 volts 60 times a second or whatever the frequency may be.
ОтветитьIndakta Fastaa Resistaa
ОтветитьIs the inductor create an a Parasitic current
ОтветитьDoesn't the inductor push the electrons the other direction compared to when it is being "charged"?
ОтветитьI like the video I understand what is going on from someone that deals with electrical everyday. But this all means nothing if I don't see a practical application and see it in use. I would recommend. adding that. Most of my knowledge, even though limited was actually learned by seeing it in use and by measuring it. Example would be seeing an vehicle ignition coil fire a spark plug and seeing the electrical work through a voltmeter, oscilloscope or amp meter.
Ответитьso what the hell is the point of the inductor tho?
ОтветитьI was thinking about it when ever I see
ОтветитьWhat's a paff?
ОтветитьVery nice man very niceeee
ОтветитьCool. Thanks for sharing.
ОтветитьBasically the inductor reduces the in rush current to protect wiring and components
ОтветитьThere are only two things you have to understand. An electron and light. The movement of electrons higher to lower spins or otherwise produces light. Other things are encapsulation. Ten power +-24. 12×2. Because Max curvature is power 12. Time is always a quantum of 24. For four dimensions 12 - 4 equals 8.
ОтветитьTo the battery DC, the inductor is just a length of wire. A inductor only has reactance to alternating current. The battery should be replaced with an AC source.
ОтветитьExcellent videos!! Please PLEASE do a video on oscillating/resonating circuits.
ОтветитьWell, that was about as clear as mud. Maybe I'm just slow.
ОтветитьWhy this inertia? Is it because electrons flows very very slow, what flows instantly is field both electric and magnetic field between particles in conductor and in core of inductor? Im asking cause lenght of wire to make coil, usefull on timings of micro seconds (power converter), lenght of wire is very short, and normally light would travel instantly, for some reason such wire is able to make huge difference in timing. Two wires close each other, with current flowing same direction makes coil, makes difference, could this because if current flows slower than speed of light? Could wire of conduction in witch current flows even slower than copper make even better coil? Clectrons are like domino effect it pushes against each other, what flows mostly is electric and magnetic field, electrons itself are much much slower than magnetic field, numbers of real electrons flowing is very very low, comparing to electromagnetic force caused by it. If such difference in speed we would have inertia effect.. I cant explain, i struggle to really understand why how, in details it works. This turbine explanation is very good though, best ever came across. Ever. What would happen if we make coil of wire in witch electrons flow faster what would be difference in material in wich electrons flow slower? Does parameters of coil varies depending on temperature?
ОтветитьIs the purpose of an inductor kind of like the flywheel on an engine?
ОтветитьThank you sir ❤️
ОтветитьWow very nice
Ответитьcan you do a video about LED driver works?
ОтветитьThe video is fine, but I don't think that simplification with "no flow over higher resistance path" is acceptable - that can plant false believe in people learning electrics during circuits simplification
ОтветитьI figured the inductor is a resistor. As current is forced through. It generates heat. Heat increases the resistance and it will eventually fail.
Ответитьpump analogue is the controller ,not the battery ...
Ответитьthank you
ОтветитьNot bad, but I generally don't like the anthropomorphizing of inanimate objects. The inductor does not "want" to do anything, nor does it "realize" anything, and so on. There are physical forces and phenomena at work, not consciousness and will on the part of the object.
ОтветитьAn inductor is an AC resistor. All the way from low frequency (50/60 Hz) up to microwaves.
ОтветитьIf you use negative to positive was the resistor on the wrong side?
Ответить👍👍👍👍👍👍❤❤❤❤❤❤
ОтветитьEven with this great explanation I dont understand real use of them. I see lot of them on electronic boards: PC motherboards, videocards, power supply units and it always amazes me.
Ответитьthanks forget what they did. easy video to follow for even the newest of minds. If I'm not mistaken they are not even really used anymore in IMLC beyond the power supply.
