Sir ap k lectures outstanding hain , mashallah, any wali hr generation ap k lectures he follow kry gy. Commendable 👍 Your way tu understanding soo wonderful, never remove to mind.
Thanks sir I have never commented on TH-cam but today I am doing because you are such a great teacher. This helped me alot as I have my board exam on Wednesday. i am gonna watch all your videos of this chap.

Ans of this question is that due to use of commutator current continuously flow through the circuit .direction of current change in coil ,conductor but in circit the current direction not change .so coil continuously move .
Sir agar coil ki side RS per downward force act kar Rahi to jab wo vertical position main jatti Hy to kon SI chaeez aos ko dobara horizontal position per lati Hy .Kun ka split rings to fixed hain coil ka sath definitely wo bhi rotate ho Jain gy coil Kay sath ...plz give my answer
Answer of question is sir that the coil is continuously move due to the inertia and also by the charge provided by the battery because the charge provider rotate the coil half and then the Inertia completes rotation
Yar jab coil half tak rotates karta to inertia say ziada force to os k QR side pa lagta hain qionk wo ab perpendicular hogay hain awar angle 90 hain and force is maximum on QR side. To per os force ka kia howa
Of course! In a DC motor, the electricity coming from the battery or power source is always flowing in one direction, which is direct current (DC). Inside the motor, there's a part called the commutator that switches the direction of the current in the motor's coils to keep the motor turning. This reversal of current inside the motor doesn't change the fact that the power coming from the battery is still direct current (DC). So, the motor runs on DC, even though the current inside it changes direction as it operates. It's like a one-way road (DC) with a switch that allows a car to go back and forth (inside the motor) while the road itself remains one-way.
Sir I have a question..When the coil reaches the exact Vertical postion we assume that it changes its position due to inertia.So sir If the intitial forces were in opposite directions then inertia should be also cancelled out
@@bebright-4840 Certainly! When the coil in a DC motor reaches the top position and starts to change its direction, it continues to move because of inertia. Inertia is like a "keep going" force, and it resists changes in motion. It doesn't cancel itself out; rather, it helps keep the coil moving. The coil changes direction because of the motor's design and the interaction between its magnetic parts, not because inertia cancels itself.
Wo vertical position may kasy change hu ga ap TU half rotate kar ky current ki direction change karhy hai 180 degree pay lakin wu TU 90 degree pay hy ruk JAYE ga plz is ka answer bataya ga
Sir the ans is that it will rotates due to inertia. Because everything in motion can't shop immediately if external force is not allied so the coil will rotate by inertia.
Respected Sir, Aik question tha jb coil 90° tk move krti ha wo coil may current ki waja sy ha , but jb coil 90° to 180° tk move krti ha us wqt tu coil magnetic field may vertical ha, tu us wqt us pr konsi force lag rhi hoti ha? Current direction aur coil location tu after 180° k bad change ho gi, phir coil again move kery gi 90° tk , but 90° to 180° degree tk kesy rotation hoti ha coil may ? Kindly Sir guide us all?
90 degree pr pohnch kr current ka flow stop ho jata he Force lagni stop ho jati he But due to inertia coil move Krti he Phir inertia ki wajah se move krke commutators change hote hen Commutators ke lehaz se current ki direction change Ho jati he But overall coil me current ki direction same rehti he Phir again whi process coil me current flow krta he force apply hoti he 90 degree pr pohnch kr current stop Force stop or phir inertia ki wajah se move krti he coil
Sir ap ne kaha ke hamein current ki direction change karni ho gi Tu agar ham commutator ko use karne ki bajae ac current use karen tu current ki direction khud hi automatically change hoti jae gi
Fleming's Left-Hand Rule is indeed a key concept in understanding the operation of a DC motor. This rule helps determine the direction of force or motion in a current-carrying conductor when placed in a magnetic field. When applied to a DC motor, it helps explain why the motor rotates. In Fleming's Left-Hand Rule: - The thumb represents the motion or force direction (mechanical motion). - The first finger represents the magnetic Field direction. - The second finger represents the current direction. When a current flows through the coil of a DC motor (represented by the second finger), it creates a magnetic field around the coil. When this coil is placed in the magnetic field of the permanent magnet (represented by the first finger), the thumb (motion) will point in the direction of rotation. This rule illustrates the interaction between the magnetic field created by the current in the coil and the external magnetic field, leading to the motor's rotation. So, yes, Fleming's Left-Hand Rule helps explain why DC motors rotate by showing the relationship between current, magnetic field, and the resulting mechanical motion.
Sir we change the direction of current via commutator so it is okay but how the location of coil change ? Beacuse due to both the force direction remain same
Plz Ye Diagram kesy banaty han iss py bhi ek Playlist banaen ,,, Kis type k Board Markers use krty han or Writting kesy improve kren hum White Board py ,,, 👍
Sit mare aik sawaal ka jawab da k ap ne kaha k coil 90 se zaida rotate nahi karee gi kyo ka wire connected to batery toot jai gi laiken book ma bataya ha ka b/c the forces are still up and down and balanced to woh to pehla bhi balanced thi matlab ye hua k coil ko rotate hi nahi karna chahia tha 😢😢😢
Sir g ye is wjaah se ghomti rehti ha kyon k hum coil mein sirf ik loop istamal nai karte balke buhut se loop istamal karye hain jo gool sa coil bana deta ha is liye jab ik loop ki force khatam hoti ha to us se agle loop ki force shuru ho jatu ha
Sir ap.nay kaha k ye serif 90 angle tak rotates karae ge awar seraf 90 tak rotates karny say to split rings Chang nahe hosakte pura 180 k ilawa to per ye rotation continues kissable rehta hay
Nahi current ki direction ka matlab haii coil mein current ki direction chang ho rahi hai Ac mein terminals ki polarity Change hoti hai yani terminal pehlay positive tha phir negative ho jata hai
Jazakallah Sir...
I have never seen such kind of teacher like you in my life...

If DC motor works on DC current then why current changes its direction.

Sir why don't we use AC it will by itself change the terminal and current direction
And there will be no need of using split rings?????
Nice question.if you find its answer then please also tell it to me

Answer of question is sir that the coil is continuously move due to the inertia and also by the charge provided by the battery because the charge provider rotate the coil half and then the Inertia completes rotation
Nhi hai yaare asy bat balky direction of force constant rahta hai bas is wajah say continuously rotate hota hai
@@murtazaalian9831 no uska sahi hai
Yeah it's right...
Ur right but according to the book it says that direction of the current changes even tho you make more sense
Yar jab coil half tak rotates karta to inertia say ziada force to os k QR side pa lagta hain qionk wo ab perpendicular hogay hain awar angle 90 hain and force is maximum on QR side. To per os force ka kia howa

when loop is perpendicular to the magnetic field why net force is zero? ap ne kaha tha ke jab perpendicular hoti he wire to maximum hoti h force

Kindly Sir guide us all?
Same ques ..
90 degree pr pohnch kr current ka flow stop ho jata he
Force lagni stop ho jati he
But due to inertia coil move Krti he
Phir inertia ki wajah se move krke commutators change hote hen
Commutators ke lehaz se current ki direction change Ho jati he
But overall coil me current ki direction same rehti he
Phir again whi process coil me current flow krta he force apply hoti he
90 degree pr pohnch kr current stop Force stop or phir inertia ki wajah se move krti he coil
Theory leki Hoti sir To our acha hota🥺❤️
Jazak Allah 🥰 sir
Its Simple . At 180 degree situation becomes same.. By repeating this you are making needlessly Complex
Thank you so much sir ❤❤❤❤❤
Sir ap ne kaha ke hamein current ki direction change karni ho gi

Very good way of teaching
Answer is: because of split rings.
Sir kia ya continuous rotation in rings ki wajah se hota hai
Sir we change the direction of current via commutator so it is okay but how the location of coil change ? Beacuse due to both the force direction remain same
