I have to say, you saved my day and my curiosity. I was so painful to understand why the scr fullwave bridge controlled rectifier can allow current to flow while the voltage is in reversed biased. You're such a great teacher!
Thank you very much for all your great educational videos....i have a question pls : as you said at time=0+ the induced inductor voltage will be nearly infinity , so shouldnt that large induced votage induce large current that would overcome the original current from the battery? , and hence the current will be anti clockwise ?....thank you and looking forward for the answer .

Hi, there sir, for the lamp to start, the starter has to be closed, yes as you said, when the light is on, current passes through the lamp, yes as you said, when the lamp is completely lit up, current flow through lamp, I agree as you said, what happened next is starter cools down and closes, my question is, due to this action why the lamp won't flickers, please reply.
Thanks for the session. Please explain. What is the normal position of starter bulb? is it normally open? why it is not triggering even after the lamp comes on? the voltage will stay accross the starter always. Thanks
Hello Sir.. I am currently pursuing Btech in electrical engineering and your lectures are amazing. It has been a month since you did not upload a video. I humbly request you sir to please upload new videos soon.
Thank u so much pisquare Academy...i really clear my all doubts regarding inductor....i salute you sir and keep it up for make our future more brighter...thank u again
Because, no rate of change in current in case of DC. so inductor allows DC without any opposition. Stay tuned to our channel for more such videos, the more you Share these free lectures "more we Upload". For every 100 clicks on share we will upload a new interesting lecture.
Sir, I have a doubt that may be silly, the starter will on and off on its own way to see the high voltage to glow the bulb. So how will do that action in starter.
Feeling proud to subscribe ur channel.. Bcz of u people efforts I am good at basics of electrical.. Thank you so much sir.. Iam elder than u but again feel happy to call you as a sir👍👍👍👍
Think of Inductor as a large body of mass which has a huge inertia. When you apply Force, it doesn't move initially. Similarly when it is in motion, when you apply Brakes, it doesn't stop immediately.
@@RizwanKhan_99 Well Induced voltage is less than the applied voltage and it's not instant, it lags source voltage by 180°.You must have learnt that in transformer we take primary voltage as Vs-Vinduced, that's the reason.
Great video. I like to explain change in current as it relates to energy. Since energy is stored in proportion to current squared we can not have an instantaneous (time-less) change in energy. Energy can not move in 0 time. So current can not jump.
So we need to close the switch gradually so that di/dt could become low and that gives less back voltage and we don't see any spark.so the question is ,is there any kind of switch available or we need to put capacitor across the switch so that we don't see the spark
Nice explanation Sir. But my doubt is whether indicator will work for D. C supply.....?(d.c supply has been connected for indicator during starting of tutorial)
You're explanation is awesome sir You are doing a wonderful job by sharing your knowledge with us thank you very much sir.please explain the charcteristics of all motors and generators sir
Sir what will happen if a distribution transformer 11kv/440v is connected the other way i.e its secondary side is connected to 11kv line and primary to household loads (assuming that bushings other switch gears are not damaged )
In an inductor, when current decreases, the applied voltage and the EMF have the same direction to counteract the change .which means the two EMF would produce magnetic field in the same direction.Would that not violate lenz's law?(Magnetic field exert force in opposite direction
Sir I have an Questions Regarding Capacitance.. Is there any capacitance in a laminated core of a machine - Because it also serves the same Theory of Capacitance, 2 metal plate and a non conducting material in between the plates.. Please make it clear to me, I have a confusion regarding this..

sir ur explaination is super but I have a doubt in tube light at turn on time first starter opposed current flow & some time delay took place in that movement ends of florocent buld has heated and released some electrons in side tube & bulb glows till here ok but while we turn off the supply why dont we observe sparks in the starter sir could you please explain how starter is behaving at t- time and t+ time t is before turn off thanks for a good conceptual vedio
u r not touching the starter. u only press switch. but starter is making contact on and off why? because they r making contact due to thermal expansion. at first when the bulb is not glowing, all current has to flow through starter. the moment the starter gets enough heated up the gets disconnected and u see spark and the bulb glows. now after the bulb glows the current has another path to flow. so current at starter reduces and starter gets cool down. but this process repeats until the bulb is fully established. but here is a little wrong in the picture shown. it showed the starter ends get disconnected when bulb is established. but starter ends cools down and makes contact. very little current also passes through that as this current is not enough to heat up the starter again. so while switching off when u disconnect power, the inductor created high voltage is absorbed by the still existing path between the bulb ends. so u don't see spark while switching off. hope this helps...
@@rifatchowdhury8043 i think u are going a little wrong brother u said about "thermal expansion." and let me clear u with that in starter when the contacts were open how thermal expansion is possible..? Bcoz H=I2rt joules law of heating. So when terminals are open I=0 means H=0 so no heating would be there then how can u say it is thermal expansion..

This is such an underrated channel.. I dont think there is any teacher in India who would do such an in deoth analysis of inductors.. Thank u sir..
Oh, no. How brilliantly explained the concept of inductor. Hats off to you genius.
Awesome ....
I regret not taking engineering seriously.....its all over now.....
You are the Best lecture I have ever came across.......

understood polarity of inductor only after watching your video.you explained clearly how current is opposed .great job!
I have ever seen such a video on electrical engg concepts. Congratulations. Keep up the good work 👍
Very well explained. Very clearly demonstrated. Thank you Sir.
Thanks for the session. Please explain. What is the normal position of starter bulb? is it normally open? why it is not triggering even after the lamp comes on? the voltage will stay accross the starter always.
Thanks
Super sir.... I want to know one thing... What exactly being inside the starter?
You r an excellent teacher.
GREAT EFFORTS.GREAT TEACHING SKILLS.FANTASTIC.
This video is very useful.thank you PiSquare Academy
Awesome attempt sir...could you please explain about why capacitor doesn't allow sudden changes in voltage
Hello Sir..

Your channel is a good source, to know more common & important things about our beautiful electrical engineering
NAMSKARAM GURU JI YOU ARE REAL GURU WITH REAL KNOWLEDGE
It will be more helpful if u make a video on capacitor.. and capacitive load..
Thank you for the video . It is really helpful to improve the knowledge.
I will watch your all videos and clarify whatever the doubts from the three years of graduation in eee
So nice and educative sir
Very good Explanation Sir, I have one more doubt why inductor allows DC,and blocks Ac ?

The world's best teacher thanks sir
Sir, I have a doubt that may be silly, the starter will on and off on its own way to see the high voltage to glow the bulb. So how will do that action in starter.
service to nation is extraordinary idea and very good expiation sir.such persons needs to our country.ur name will be long forever forever.
Great explanation but why inductors used in different circuit board, to block ac current?
Well explained, could you teach electronic ballast working in all ckts
Feeling proud to subscribe ur channel.. Bcz of u people efforts I am good at basics of electrical.. Thank you so much sir.. Iam elder than u but again feel happy to call you as a sir👍👍👍👍
Best electrical engineering channel on RUclips

Awesome 👏,,a big applause from Chicago
how the starter is working?.........and thank you so much sir ..for making such videos! you are a real hero!
Perhaps the best explanation ever seen
If induced voltage (back-emf) is equal and opposite to applied voltage, what drives the current?
this is my question since a long time
@@ashishjha9961 bro i passed engg 11 yers ago and im still clueless
@@RizwanKhan_99 Well Induced voltage is less than the applied voltage and it's not instant, it lags source voltage by 180°.You must have learnt that in transformer we take primary voltage as Vs-Vinduced, that's the reason.
Nice technical explanation but what I feel more simple in easy form required to be explained all good luck

hello sir ....,now a days we are using mostly electronic chokes.....so...how can we achieve inductor operation through an electronic chip......?
Ur lecturs are awesome sir. this video's are more than helpful for every electrical engineering student s
So we need to close the switch gradually so that di/dt could become low and that gives less back voltage and we don't see any spark.so the question is ,is there any kind of switch available or we need to put capacitor across the switch so that we don't see the spark

But my doubt is whether indicator will work for D. C supply.....?(d.c supply has been connected for indicator during starting of tutorial)
NICELY EXPLAINED ...COULD YOU TELL MORE ABOUT STARTER?
thanks for the video cleared the concept
Very good teaching. Please continue sir
clearly understand how inductor works !!!!👌👌👌🙏
thank you sir ...
very nice.but how starter turn off after light glowing
You're explanation is awesome sir
You are doing a wonderful job by sharing your knowledge with us thank you very much sir.please explain the charcteristics of all motors and generators sir

Sir you done a great job for electrical engineering you are my god
Very good explanation .
How the starter is repeatedly closed and opend practically?? Is this due to alternating current we supply?? Please clear this
Can we do the same with DC supply. Will it glow
This was a truly excellent presentation . It was clear , concise and extremely interesting. Thank you for your excellent teaching.
Thank you very much for your presentation. I understand stood lot of unknown things
really really really really amazing.......goosebumps to ur explaplanation.....keep tutoring
Thank you very much sir..Now I have clear concept about inductor

Thank you sir .
You are doing very great service to people.
Sir can you tell us about the best books with their name of writer of the main subjects in Electrical engineering. That will help me a lot .
Sir I have an Questions Regarding Capacitance..
Is there any capacitance in a laminated core of a machine - Because it also serves the same Theory of Capacitance, 2 metal plate and a non conducting material in between the plates..
Please make it clear to me,
I have a confusion regarding this..
Sir please tell me,what happens if we given DC supply to this ckt
Really sir amazing and best example also clear my confusion
Dear sir why we use inductive load in industry not resistive or capacitive load?

Sir,
Transformer phase displacement topics my doubts for Dyn11 what is current and voltage, how they select the transformer in factories.
sir, really superb explanation ever I heard...keep going 👍 Eger for your upcoming vedios..

but I have a doubt
in tube light at turn on time

which part makes the bulb permanently blown up ? whether its the filaments or the gas present in it?
Its due to the Heat! heat generated by the filament
Sir can u explain about AutoCAD systems working in switchyard(133kv)
Service to the nation excellent thought👍😊
Sir please explain how that fluorescent lamp work with electronic chock with out that starter, how the light emitted by LED s. Thank you so much.
sir pls tell us how to calculate angle in directional relay..??
what is the use to connect a capacitor in parallel to the starter
awesome video sir plz make some videos on electronics components
Please do video on why pf reducing on more induction load, and how it improves by placing capacitor bankd
Nice explanation
Sir, what is the range of the current consumed by the tube light when it is in the on condition ??
It depends on its wattage value, In general, tube light (fluorescent lamp) ranges from 30 to 40Watt.
Loved the way you teach...
