Your water wheel analogy of an inductor is brilliant! Further, I admire and respect your ability to explain things in simple terms without dumbing it down. Graphics are fantastic, by the way.
@@razen4758 Most common practical uses of inductor are as filters, like low pass filters, so they filtered out higher frequencies(inductors are known that with higher frequencies they become like resistors for current flow because of opposed magnetic field.. More advance use of inductors for example is transformers where magnetic field of first primar inductor(coil) go through wires of second secondar inductor and generate lower voltage current of same frequency. Also lately there are very popular inductor cooktops, where they use energy of electro magnetic field, to generate heat on right cookware, where coockware presenting resistance to that magnetic field, so they heating up.
Great explanations! You might add that inductance can be tricky to measure because inductors tend to be one of the more "imperfect" components we typically deal with in electronics. Inductors often include a lot of resistance.

Great explanation about what it does in isolation, but an integration example would be very helpful. How is it used in a DC transformer? etc. I think this is the only thing that is missing from your great videos about electronics. Thanks!
This is a really good explanation of what an inductor is and what it does, however, they(inductors) as well as capacitors act different with DC as they do with AC and have different applications with both types of voltage sources. Inductors are a short circuit to DC and have resistance to AC (reactance) while capacitors have totally opposite properties and are resistive within DC circuits bit offer low resistance paths(i.e. SHORTS) to AC voltage sources. In AC circuits, this property is called either inductive reactance Xl = 2*pi*F*L , or capacitive reactance Xc =1/(2*pi*F*C). Caps and inductors are typically used together in series and parallel combinations to form different types of filters such as band pass, band reject, and high or low pass filters(depending on how they're connected to the circuits output either allowing a freq range to pass to the output and on to another stage, or route the tuned freq of the tank circuit to ground to act as a filter, OR, as an oscillator . When combined with resistors, the total combined effect is called impedance, denoted by the symbol Z and is the square root of the sum of R squared plus X Squared .
Good explanation. The reason for this behavior is explained at 5:53. I wish these details of reactance, AC vs DC, and applications were added. Edit: For those learning, DC has no change in current so inductor just passes current along and acts like a wire. AC has a change of current so the inductor opposes the change and acts more like a resistor. Inductor is like a frequency dependent resistor XL=jwL=imaginary number*frequency*inductance.
Where were you and your videos when I was completing my engineering! 😣 Inductance and Capacitance was something I never fully grasped during my academics! Here now I can literally visualise how things work there.. Thanks a lot for sharing such amazing knowledge 😀😊
Truely remarkably good video ! Inductors are complex, for usually its a coil with a current that creates the magnetic field. and other times its an Antenna recieving a magnetic field, creating a current . An inductor stores a magnetic field. The Volt is instant but the Ampere is Delayed and ramp slowly, fade in, once the switch is in. Switch opens and the current fades out in a ramp over time. Just opposite of a Capacitor, where the Ampere charges first, steep. but the Voltage rises in a slow ramp . Phase Compensation . Henry in a coil would be the same concept as Farads in a cap. Its energy stored is one thing, but the Time it takes to deplete the energy is depending on the resistance of the circuit with load . The magnetic field in a coil would deplete even if both coil ends are completly removed from any circuit, because its driven by the current. Once the current is removed from a coil, it takes time for it to fade out, time for the electrons to settle, the time sequence to reach ground state or Quantum Inertia ! depending on L = henry . I suppose you can call that eddy currents as well as Back EMF, as well as self inductance.
Thanks, Paul! One of the best explanations of an Inductor I've ever seen. Thanks for the effective analogy and diagram. Very helpful. Anyone learning about circuit elements should take a look at this.
I recently re-ignited my passion for computer engineering (and electricity altogether). Your recent videos couldn't have come at a more convenient time. For some reason I've been struggling with AC principles and semiconductors but I guess its because I'm a tactile learner and I like a nice quiet environment when I'm learning. Time to binge watch some more videos!

I'm glad youtube suggested this series to me, I've seen several technical explanations of various components but these make it so much easier to understand. Great job.
Forget College and watch these videos,awesome demonstrations and explanations. Paul is great at explaining everything ,I have been an electrical engineer for 30 years and watching the videos have been my best teacher.
Great explanation and analogy on the operation of inductor! However, I'd like to point out something that I've noticed in most lecture, that is they always provide a current path for inductor when the switch is off. One critical factor for using an indicator is to also understand what happens if a current path is not provided and what the consequences are. I've noticed many people using inductor without knowing what "kickback voltage spike" is. It would be best if the video includes this part as well.
Yes we used to make electric shock machines in our lunchboxes at school using choke coils out of old TV sets (cathode ray ones). We would have two handles instead of the bulb. A 9v batter and a switch. The collapsing field generated such a high voltage that you could get a circle of kids with the one at each end holding one handle each, to all jump from an electric shock. No idea what the voltage was... we just thought it was hilarious.
Get ready for a shock. Electron flow is not what actually happens in a circuit. It's just as 'wrong' as conventional current. Ask any quantum physicist.
Watching your video is better than all.my professor when i was in college...the next thing you need to do..! See how you can give a diploma to your loyal viewers and subscribers..LOL..you are amazing genius guy..!!!
That’s the difference between a technician and a technologist. My dad was a technical guy and taught me electron flow. But when I studied to be an electronic engineer, my professor, Dr. Ludeman, taught conventional flow. He has a saying when questioned about this, “I’ve never seen the color of an electron.” (He has a PhD in physics.) What he means is why does it matter if you can think both ways and easily switch between either?
second year electrician and you are literally saving my brain. I don't think I know more than two or three journeymen who know all of this lol. and they're not as great as explaining it. thank you.
Interesting how you demonstrate both capacitors and inductors with DC. I have a tendency to always think that capacitors are for amperes as inductance is for volts. Never seen the water wheel theory before but it's good. Looking forward to seeing your tutorials when you talk about inductance on AC
1:45 The proper Electron flow direction can be a confusing idea to some in the beginning. It helped me to think of the "hot" or "+" side as being like a vacuum drawing up the electrons.
I was confused at first, thinking "isn't this what capacitors are supposed to do?" But capacitors resist changes in voltage, not current. And I now understand the difference much better. Capacitors build up a charge, the charge remains when the battery is disconnected, but the voltage difference is still there, now provided by the capacitor instead of the battery. For an inductor, the magnetic field the generate keeps existing for a little while, and this magnetic field induces a current in the wire when the battery is disconnected, thus keeping the current going for a little while longer until the battery collapses. Thus capacitors provide voltage, and inductors provide current.
I love your video! More of this please since I’m going to take the licensure exams for Electronics Engineers in the Philippines on April 2020. Thank you!
Love the hydraulic analogy illustration. As an electrical guy who has to explain electrical concepts to mechanical guys all the time, I can’t overstate how useful the hydraulic analogy is.
Thanks for this explanation. Can I ask for the examples of usage to be explained as to "how" those applications are realized, for example filtering. How does inductance realize filtering? That was the bit that was missing for me. Also, the relationships of inductance to other phenomena would help understanding on how these can be put together to form a circuit with some function
What I am not grasping is what is the purpose? why do we need an inductor in a circuit? The more I learn about electronic components, the less I know about them it seems. I understand how it works, but why is it needed?
Honestly it's kind of the same for me. What I got from this is that an inductor basically acts the same as a resistor and a capacitor combined, so the only reason to use it would be to save space I guess? The only difference to a cap and res combo would be the way it reduces the flow, since it acts as a resistor while and after being charged, therefore not delivering the full power while connected, but then acts a cap and gives the stored energy back, whereas a resistor would constantly resist the same way and the cap not really interefering much with the current. It's confusing indeed
To store energy and help the process. Watch the pump part a few times. Don't like to type on my phone, but it isn't that difficult to understand. Don't over think it.
Inductors allow to store energy for converters to work (buck, boost). They can be used as a low pass filter (remember its impedance is jwL, greater for higher frequencies because a greater variation in magnetic flux generates a higher voltage that oposses it), for example it can avoid high frequencies from noise from reaching the voltage source by making the path to it have a greater impedance for high frequencies that the path you want to redirect them to. And well obviously as a part of a transformer which has multiple uses.
The problem is that what we call "electronics" is in reality just various applications of Theoretical Physics - and the physics behind these devices is generally quite complex. Sadly, to really understand what and why one needs a solid background in University level Physics. And even then, some of the phenomenae have multiple theoretical models for their explanation! Simple explanations based on analogies to other better known physical systems such as plumbing and water have limited usefulness and can often lead to false assumptions regarding real-world circuits...
I am really enjoying these videos. I work in the power industry (steam generation side) and I've always been mystified about how the electrical side works. Having said that, I used to work for the railroad as a locomotive engineer operating DC/DC diesel electric locomotives. I never really understood why the locomotives had to make transition (change the electrical connection between the generator and traction motors) as the speed changed. Something to do with back EMF, but it was never really explained.
The magnitude of voltage produced by a changing magnetic field is directly proportional to its rate of change. Abruptly disconnecting the battery --> abrupt change in coil current --> momentarily high rate of magnetic field change --> voltage spike.
Wait does the electron flow to the bulb reverse when the power source is disconnected from the circuit? Wouldn't that cause problems if the component had a certain polarity?
I think it would cause problems for components that need DC. However I'm pretty sure that inductors are often used in series with the load, unlike the example in this video where the inductor is parallel to the load, and causes the current to change direction when the battery is disconnected.
*summary:* - an *inductor* is a component in a circuit that stores energy in a magnetic field, and can quickly release it - the water wheel analogy is excellent to think of as an inductor (it takes time to "start up", and when current is shut off, it will keep current moving till it loses "inertia") - moving electrons generates a magnetic field (thus electrons moving in a wire produces a magnetic field) - putting wire in a coil causes a bigger magnetic field to be generates - inductors have "current inertia" (they don't like change in current - if current is trying to increases, they will make it harder for that to happen by "sucking up" some of the current as an increase electromagnetic field, if current is trying to decrease, they will add current - but this uses up some of the energy stored in its magnetic field) - inductors "smooth" out the start and stop of current - inductors in circuit boards often have a casing to shield other components from its magnetic field
You could for example use a inductor in line of a power supply, for example for a mobile phone or laptop. imagine you put the supply in the socket. Often, you see a spark while you insert the supply. this could destroy your smartphone if you didn't have a induction which blocks a spike in the current flow.
Thanks sir, for making us understand what an inductor is. I was very frustrated as to what does this material behave in contrast to capacitors or diodes. Nevertheless, our school really never focused on what an individual component like an inductor is but blindly explained the combination of inductors and other appliances in the circuit like oscillators, series lcr circuit plugged to ac source etc. Anyway, thank you for the knowledge, sir. I hope this channel would grow even more in subsequent time.
“Remember electricity is dangerous and can be fatal” I’m watching this to kill time while I quickly charge one of my e-cigarette 4v batteries with an 18v DC power adapter
Capacitors and Inductors do the same thing.... they store energy. Capacitors use chemistry to make a small electric field to store up electrons. Inductors store energy in the form of a concentrated magnetic field. Both take time and electric current to "charge" but behave differently once they're charged. A capacitor acts like a resistor once it's charged, but an inductor acts more like a straight wire once it's charged. When power to them is removed, they then begin to discharge, assuming the energy they've stored has somewhere to go. Both discharge at different rates/profiles.

What I am not grasping is what is the purpose? why do we need an inductor in a circuit? The more I learn about electronic components, the less I know about them it seems. I understand how it works, but why is it needed?
Same here
Honestly it's kind of the same for me. What I got from this is that an inductor basically acts the same as a resistor and a capacitor combined, so the only reason to use it would be to save space I guess? The only difference to a cap and res combo would be the way it reduces the flow, since it acts as a resistor while and after being charged, therefore not delivering the full power while connected, but then acts a cap and gives the stored energy back, whereas a resistor would constantly resist the same way and the cap not really interefering much with the current. It's confusing indeed
To store energy and help the process.
Watch the pump part a few times.
Don't like to type on my phone, but it isn't that difficult to understand.
Don't over think it.
Inductors allow to store energy for converters to work (buck, boost). They can be used as a low pass filter (remember its impedance is jwL, greater for higher frequencies because a greater variation in magnetic flux generates a higher voltage that oposses it), for example it can avoid high frequencies from noise from reaching the voltage source by making the path to it have a greater impedance for high frequencies that the path you want to redirect them to. And well obviously as a part of a transformer which has multiple uses.
The problem is that what we call "electronics" is in reality just various applications of Theoretical Physics - and the physics behind these devices is generally quite complex. Sadly, to really understand what and why one needs a solid background in University level Physics. And even then, some of the phenomenae have multiple theoretical models for their explanation! Simple explanations based on analogies to other better known physical systems such as plumbing and water have limited usefulness and can often lead to false assumptions regarding real-world circuits...

Thank you!
The old water analogy. Yes, it helps but I got it backwards once and flooded my basement when I cut a pipe to stop the flow.
lmaoooo
Very good explanations. I wish I had this approach back in my youth learning basics. Keep it up. 👍
Hey Paul, can you make a video about how the diesel generator work? Im talking about excitation system, avr and so on. Thank you:)
Oh yes this is definitely coming, be for a while though.
I am really enjoying these videos. I work in the power industry (steam generation side) and I've always been mystified about how the electrical side works. Having said that, I used to work for the railroad as a locomotive engineer operating DC/DC diesel electric locomotives. I never really understood why the locomotives had to make transition (change the electrical connection between the generator and traction motors) as the speed changed. Something to do with back EMF, but it was never really explained.
So well explained, i m knew to electronic and by far the best channel...thank you so much
me: god help us.
youtube: recommended
very nice video, especially the wheel analogy part
The reactance of a inductor would be invisible from the power from a battery
Nice video dude...
Simplest explanation and better than formal class study.
Doesn't a collapsing magnetic field cause a voltage spike before it goes out?
Only if it can't maintain the current
kimrkarl go to sleep
yes it does. that's why it's used in boost converters.. he did not cover that..
No, read up on a transient response
The magnitude of voltage produced by a changing magnetic field is directly proportional to its rate of change. Abruptly disconnecting the battery --> abrupt change in coil current --> momentarily high rate of magnetic field change --> voltage spike.
This 10 minute video explained inductors much better than my textbook thank you!
Wait does the electron flow to the bulb reverse when the power source is disconnected from the circuit? Wouldn't that cause problems if the component had a certain polarity?
If it's a light bulb designed for an AC system then it's already used to current that's constantly changing direction.
I think it would cause problems for components that need DC. However I'm pretty sure that inductors are often used in series with the load, unlike the example in this video where the inductor is parallel to the load, and causes the current to change direction when the battery is disconnected.
I have seen some videos looking for a good explanation... ..this is the right one. Thank you.
You made a great analogy, but you didn't explain why I would want an inductor in a circuit.
8:56
funny comment🙄. ONLY you know what/why you want an inductor in your circuit🤷🏿♂️
I have searched a lot and saw a lot of videos
This is the best video with the best explanation
Thanks
9:24 Say cool. Now say whip. Now say cool whip.
This is when the mouthful explanation in handbooks becomes close to useless.
It's a great video!
*summary:*
- an *inductor* is a component in a circuit that stores energy in a magnetic field, and can quickly release it
- the water wheel analogy is excellent to think of as an inductor (it takes time to "start up", and when current is shut off, it will keep current moving till it loses "inertia")
- moving electrons generates a magnetic field (thus electrons moving in a wire produces a magnetic field)
- putting wire in a coil causes a bigger magnetic field to be generates
- inductors have "current inertia" (they don't like change in current - if current is trying to increases, they will make it harder for that to happen by "sucking up" some of the current as an increase electromagnetic field, if current is trying to decrease, they will add current - but this uses up some of the energy stored in its magnetic field)
- inductors "smooth" out the start and stop of current
- inductors in circuit boards often have a casing to shield other components from its magnetic field
An inductor stores energy in the magnetic field, not an electric field. Capacitors store energy in the electric field.
@@shayanmoosavi9139 Thanks! I corrected it :)
Wow, just wish these videos were around when I was younger. Really understand how this guy explains things. YaY!
good explanation however, still not sure why you would want to use one or why its necessary to have one.
You could for example use a inductor in line of a power supply, for example for a mobile phone or laptop.
imagine you put the supply in the socket. Often, you see a spark while you insert the supply. this could destroy your smartphone if you didn't have a induction which blocks a spike in the current flow.
@@MrFrakyfriday ah ok. so does it basically "smooth" the energy flow out, almost like a shock absorber?
@@jessemurray1757 yes, exactly!
MrFrakyfriday brilliant! Thank you sir!
Thanks sir, for making us understand what an inductor is. I was very frustrated as to what does this material behave in contrast to capacitors or diodes. Nevertheless, our school really never focused on what an individual component like an inductor is but blindly explained the combination of inductors and other appliances in the circuit like oscillators, series lcr circuit plugged to ac source etc. Anyway, thank you for the knowledge, sir. I hope this channel would grow even more in subsequent time.
RLC or LCR meter? commentary says one, video indicates the other! otherwise great vid, thanks
Commonly known as an LCR Meter Brother...
Noticed that too

Doesnt bother. They sell you the same one whether you ask for LCR , RCL, ,,,,,
Excellent video! The water wheel is the best analogy I've seen to help me understand the concept! Thanks!
I know you’re more electrical, but if you could do transistors and mosfets. That would be great

Thanks, first time to see example of water wheel and it makes perfect illustration.
RLC or LRC meter?
LCR * was definitely thinking of something else while speaking
@@EngineeringMindset 😄 thanks
It's the same thing, really.
very nice video! Has been a fan of this channel since 2022!
“Remember electricity is dangerous and can be fatal”
I’m watching this to kill time while I quickly charge one of my e-cigarette 4v batteries with an 18v DC power adapter
No just killing time. It can kill. See my comments.
This is so helpful, taking a circuits class and its really hard to conceptually understand what is going on in a circuit by looking at a plain diagram
I understood the capacitor video. This one confused me.
Mike McMac me too ... it’s just confusing what inductors would be used for
Capacitors and Inductors do the same thing.... they store energy. Capacitors use chemistry to make a small electric field to store up electrons. Inductors store energy in the form of a concentrated magnetic field. Both take time and electric current to "charge" but behave differently once they're charged. A capacitor acts like a resistor once it's charged, but an inductor acts more like a straight wire once it's charged. When power to them is removed, they then begin to discharge, assuming the energy they've stored has somewhere to go. Both discharge at different rates/profiles.
