Current always flows if there is a loop path for it to, how much is determined by the path resistance where all paths sum to supply voltage over total circuit resistance (It = Vs / Rt). In the case of the inductor, however, there is a time component; electrical energy is first stored in the form of a magnetic field, which produces an initial opposition to the flow of current (Back EMF), once the magnetic field is fully formed (measured in micro-seconds, you wouldn't 'see' this), it acts like a very low value resister, essentially a short circuit. Note: this is not a practical circuit, it's only use to simply illustrate the behaviour of an inductor.

As an EE, I think this video would have benefitted from an explanation of what inductors are, and why they operate the way they do, before you get into the how. Touching on Len'z law would have helped a lot

As Feynman put it, "Why" questions are tricky. Of course you can say Lenz's law is the reason why inductors work the way they do, but then out of a sudden thousands of new questions emerge: WHY does Lenz's law hold? WHY does the right-hand rule hold and not a mirrored version of it? WHY are magnetic and electric field correlated at all? Etc etc etc... IMO it's perfectly legitimate to stick with the HOW in the beginning to avoid complexity explosion LOL

​@floorpizza8074 But without explaining its purpose, what it does, Why it is there? To novice it has no meaning. It's in one ear and out the other...ultimately learning nothing. I am a novice and I still have got no idea. So it creates a magnetic field and then it collapses. Well that's great to know... yay.

Inductors are primarily used in AC (and switched DC) circuits but explaining how they work at a basic level is very difficult in AC circuits (because you end up having to explain reactance, impedance, phase shifts etc.). The battery + inductor + light is not a practical circuit, but it does eloquently explain how they work (current 'inertia' via magnetic field), which is the purpose of the video.

It’s interesting you used the word inertia, I’m just a beginner with electronics but have been welding 25 years and when I took a electronics 101 course my gut told me the inductor gave the current inertia so it’s nice to hear you kind of confirm that in so many words.

I have no word to explain how much I am impressed by your tutorials. Modern institutes should learn from you. How to teach their students. I am so excited. you guys absolutely incredible. 👏 ❤ love you guys.

This is hands down the most amazing and intuitive approach I've ever seen on inductor.kudos man! you guys are the reason I got my interest back at Electrical Engineering

To 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.

An inductor is an AC resistor. All the way from low frequency (50/60 Hz) up to microwaves.

It seems like what you are describing is a capacitor. How would you describe that an inductor can act like a capacitor and how are they different? I normally think of an inductor as a device used to cause current on another, non-electrically connected nearby circuit while a capacitor stores energy like a battery within a circuit typically used to reduce variance in voltages over time or to provide some electrical bursts for some applications. Appreciate your videos and helping me better understand what you are trying to share here. Thanks.

I will try to explain the difference between an inductor and a capacitor to you in the simplest way that I know. A serial connected inductor is like a flywheel. It takes some energy to get it started but when it is started it is easy to keep running. The only thing that really would stop it if left on its own is the resistance in the bearings. When it is spinning it has stored energy and to stop it it must give out this energy. The electromagnetic force in the inductor works in the same way. It keeps on resisting change. A parallel inductor works as an open circuit. it will take some time to get the flywheel to spin so that there no longer is any resistance. A parallel capacitor on the other hand is more like a big water tank. If you poor in water it takes some time before it is filled up. It also stores energy but it must be full before it has the same pressure as the input pipe. A pipe out the bottom of the tank will start up with low pressure but eventually have full pressure when the tank is full. The output will have almost full pressure all the time even though the input may be intermittent. A serial connected capacitor will allow a current immediately. It is like an already filled up tank with a rubber membrane in the middle. In many ways an inductor and a capacitor work similar. It is just that the inductor is resistant to current and the capacitor sucks in the current. The inductor has the voltage before the current and the capacitor has the voltage after the current. They both store energy.

"... electrons leave the battery, they flow and try and get back to the other side of the battery" - I get why you want to illustrate what happens using that analogy, but the student may also want to know that is not really what happens to the electrons. In reality they jostle, the electric field pushing them in a direction but the electrons that are free push against each other too. In the end the current is just an emergent property of energy transfer via electric fields.

Awesomeness

4:52 If the inductor will eventually act like a normal piece of wire with no resistance, what's stopping it from creating a short circuit?

It 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.

I see these on mini splits. Was curious what they do

so at 3:08, we basically made a short circuit? Also, why would we use inductors? What are their purpose other than having a light turn on very briefly when opening and then closing a contact?

How is this different from a capacitor

Wait how is this different from a capacitor? That also helps current flow for a short duration if the power source is shortly disconnected...

Is it possible to give Vedios on DTR faults and effects pls

Basically the inductor reduces the in rush current to protect wiring and components

There 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.

So then, what purpose does an Inductor serve? Is it similar to a Capacitor as it stores charge - or does it? It seems to work like a resistor when first given power, but then it causes a short circuit through itself. I'm confused?

This is not a practical circuit, it's being used just to simply illustrate the behaviour of an inductor. Inductors are primarily used in AC (and switched DC) circuits (filters, chokes etc) but it's hard to describe their basic function when the supply is continuously changing. Yes, they can be used to 'fill in' for supply gaps but this is rare, or rather, large transformers tend to pick up this function.

Inductors can have resistance but it's not exactly a resistor. A resistor's job is to just reduce the current flow in the circuit. But an inductor is more of a wounded coil which offers resistance at first because of its tendency to charge initially.

Doesn't the inductor push the electrons the other direction compared to when it is being "charged"?

the creation of the magnetic field, the movement of that, I assume is then opposing the current thanks to the like, the left or right hand rule, or something, cus a moving magnetic field induces a current, and the movement of the field being created by the inductor will then cause it to induce a current in the opposite direction causing impedance, thats what ive imagined happens atleast.

inductors are commonly found in dc/dc switch mode power supplies. inductors store energy in a magnetic field. if you're clever, you can build a circuit that uses a switch to turn current flow on/off through this inductor and get a higher or lower voltage on the output. inductors are also used in filtering (both signal and power filters)
