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!

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.
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👍👍👍👍
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.
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 .
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.
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
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
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 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 )
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
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.
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..
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

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.......
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!

You r an excellent teacher.
If induced voltage (back-emf) is equal and opposite to applied voltage, what drives the current?
this is my question since a long time

It will be more helpful if u make a video on capacitor.. and capacitive load..
GREAT EFFORTS.GREAT TEACHING SKILLS.FANTASTIC.
Very well explained. Very clearly demonstrated. Thank you Sir.
True service to Nation and for students of India..... Thank you so much for such simple explanation. 🙏🙏🙏🙏
So nice and educative sir
I have ever seen such a video on electrical engg concepts. Congratulations. Keep up the good work 👍
I like your way of teaching thank you so much for your help ❤ 😊 🙏 ♥
understood polarity of inductor only after watching your video.you explained clearly how current is opposed .great job!
The world's best teacher thanks sir

Very good explanation .
thanks for the video cleared the concept
clearly understand how inductor works !!!!👌👌👌🙏
thank you sir ...
Can we do the same with DC supply. Will it glow
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.
Great explaining👋👋
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
Perhaps the best explanation ever seen
sir, really superb explanation ever I heard...keep going 👍 Eger for your upcoming vedios..

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.
Great passion
Great channel
♥️♥️♥️♥️♥️
very nice.but how starter turn off after light glowing
Great explanation but why inductors used in different circuit board, to block ac current?
Super sir.... I want to know one thing... What exactly being inside the starter?
It's awesome sir. I do not have any other words to comment, thank u so much sir
Amazing effort!
How the starter is repeatedly closed and opend practically?? Is this due to alternating current we supply?? Please clear this
wonderful explanation .

Hello sir, Plz make a video for PLC
Good explanation sir
sir pls tell us how to calculate angle in directional relay..??
Thank you sir .
You are doing very great service to people.
Sir you done a great job for electrical engineering you are my god
Really nice
Thanks sir
Please tell me about capacitor
Service to the nation excellent thought👍😊
Awesome attempt sir...could you please explain about why capacitor doesn't allow sudden changes in voltage
Thank you very much sir..Now I have clear concept about inductor
Thanks sir for making our concept clear....
Really sir amazing and best example also clear my confusion
hello sir ....,now a days we are using mostly electronic chokes.....so...how can we achieve inductor operation through an electronic chip......?
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
Thank you very much for your presentation. I understand stood lot of unknown things
NICELY EXPLAINED ...COULD YOU TELL MORE ABOUT STARTER?
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.
what happen in electronic chock where we not use stator for starting lamp.
what is the use to connect a capacitor in parallel to the starter
awesome video sir plz make some videos on electronics components
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.
super explaination sir
how the starter is working?.........and thank you so much sir ..for making such videos! you are a real hero!
Dear sir why we use inductive load in industry not resistive or capacitive load?
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
