Basic Electrical Engineering | Module 5 | Back EMF of DC Motor | | (Lecture 42)

[@pkpathak2954]

Sir according to your statement armature current must be inversely proportional to back emf while you are writin Directly proportional except it your lectures are amazing for understanding to everyone.

@@swapnilshiyaniya5306 bro when backed emf is increasing the value of backed current is reduced

[@01akhilkoul37]

@@swapnilshiyaniya5306 arre so vahi toh kaha Eb is inversely prop to Ia

[@sounakroy1933]

Back emf is directly proportional to supply current aka armature current.

[@sounakroy1933]

@@SumitKumar-fz3gq when supply current I is more, it produces more magnetic field in the coil and since the magnetic field is more, stronger back emf is enduced. So back emf and I are directly proportional. But since there is a -ve infront of Eb, it indicates that the overall quantity decreases as Eb increase due to increase in I.

[@vivinlobo3091]

@@01akhilkoul37 bro, since the back emf is generated due the curent supplied, as you increase the supply current the back emf induced will also increase, but it will not be greater than the supply... when you reaarrange the armature current eq, you'll get Eb = Vt- IaRa clearly Eb is always less than Vt, supply voltage and Hence Ib( backd current ) will also be less than Ia (supply )

Kabhi nhi socha tha ki is topic me bhi itna kuch hai concept. Thank you sir is pandemic me padhai k liye aap hi sahara hain.🙏🙏🤩

[@SudiptaHazarika-jn5um]

Correction : Back emf is directly proportional to the armature's speed of rotation and inversely proportional to the armature current

[@achintkaurbatra7160]

The way you teach is sooooooo amazing Sir, huge respect for you, and with clearing every small concept at a student level. Wish, every teacher can teach like you in colleges and everywhere. GOD BLESS. :)

[@sadiyanoorain140]

24:52 you have mentioned that armature current reduces as back emf increases. Then how can you mention that armature current is directly proportional to back emf.

[@ashcatmesochroic1306]

same question +1

[@ashcatmesochroic1306]

I have also same doubt , please answer sir Ranjan Rai sir give answer

[@preparewell6406]

Yes bro ...?

[@sainarsareddybireddy6903]

That is -Eb So

[@rohitvaskel8435]

Sir ne ulta bol diya tha phele ,so don't be confused

[@mahadev1997]

OMG VERY CLEARLY EXPLAINED, THAN MY CLG LECTURERS THANKYOU RANJAN SIR

[@sudipbiswas4718]

22:29 sir armature current is inversely proportional to back emf

[@darshanamane5020]

All previous lectures in module 5 is so good. I have understood all concepts very easily.

[@villayatali1447]

Love you 😘

[@speaktruth8953]

Sare KZbin par aisi video nh hy sari confusion dur hogai thank u so much sir alot of thanks 🥰❤️

[@im_cpk]

Sir aapne to back emf ka concept feel karwa diya ... Thank you very much sir !!!

[@subhammohanty10]

😍

[@vishvasbhosale2719]

Aap bahot aacche padate Ho.. Great sir..

[@izharalam2636]

Sir you said Ia is directly proportional to Back Emf, but in the both case's (case 1,2).When Eb increases Ia start decreaseing,How is this possible?

[@prashantdhoble4547]

you are right thhey are inversly proportional

[@skkstudio1972]

Thank you sir for your amazing lecturer delivering skills...we all from Pakistan salute to you❤️❤️

[@ytshortsbykc8544]

Outstanding explanation sir thank you ☺️

[@cr3538]

Armature current (Ia) should be inversely proportional to Back e.m.f

[@dhruvgupta1740]

exactly ..thinking same

[@mdwahidur65]

outstanding lecture... grateful to gate academy for their outstanding playlist... take love❣

[@anilgadekar9111]

Sir your explain types very simple Thanks you very much

[@HarshSingh-um2tl]

Actually it must be inversely proportional sir ia and eb

[@ambujyuvi]

Sir armature current is decreasing with increase in back emf...

[@rkproduction1177]

Sir, Explainon is best of 🌎

[@nanimakakitchen6543]

Bhut achchha samjhate he sir.thanku sir.

[@sarojinipaneru9648]

Sir u are awesome ... Made electrical vry easy

[@LATESTBHAJAN656]

Thank you so much sir for explaining details ❤

[@nowrozkhanbarozai]

thank u sir. u explain very well as usual be happy sir

[@AshwaniKumar-kw7kk]

I love u sir ji aap bhot acha padhate ho

[@samitakaul6331]

one of the best teacher of machines

[@prabinkumarswain272]

Sir please clarify... According to your statement back emf is inversely proposnal to armature current..but you written t inverse statement Please clarify Your lecture is really enjoyable Thank you

[@anubhavsingh4985]

Yes I am also confused

[@anubhavsingh4985]

As the speed of the armature increases, the back emf also increases and causes the armature current is decrease.

[@MDFarid-sk9md]

Amazing lecture on Back EMF.....

[@bagriaakash3432]

Sir love you kitna acha badhate ho aap love you sir❤

Fully understandable video sir

[@sutradharitabharatkipaurad4716]

Sir armature current back emf ke unpropostional hoga n

[@piyushpriyadarshandas5630]

Sir Eb =V-IaR Then keeping v, R constant algebrically Eb inversely proportional to Ia......

[@_.animeworld._]

Correct bro sir ka thoda miss conception ho gya hai

[@Never_Engineer_Vlogs]

ThanQ sir❤

[@kifayatjamali7451]

thank you sir bht maza aya...

[@prasukjain2129]

Sir i have one question humne resistance back emf or current pta ha to ye sb ok ha ya nai kse check krege resistance kase measure krege segment ke kin point par check hogi

[@deepakbarik4039]

sir pls Synchronous motor k bare me ek video bana dijiye.

[@NeerajKumar-bf5ts]

Great 👍👍

[@Ayodhyainternational]

Very good sir

[@sureshbadadani5698]

Thank you so much sir 😊💞

[@navneetsingh6433]

great man👍🏻

[@badalsona9344]

vt inversely hoga na eb ke

[@electricalfunda4287]

Ia(Armature Current) directly proportional to (Vt-Eb)

[@indiangmv3180]

Just amazing 🔥

[@aayush270]

My doubts are clear

[@rashmiraj5197]

Its awesome sir

[@yrulookinghere509]

sir back emf and current ki eqn mei back emf ka sign toh -ve hai toh wo directly kaise proptional hoga

[@barkhalahori3416]

Sir agar back emf Bodega toh vt-eb ki value toh kum ho jayegi..toh armature current bhi kum hona chahiye n

[@sutradharitabharatkipaurad4716]

What is means of torque on armature please reply, 🙏

[@harishnotyal4778]

Gajab

[@SunilKumar-fs4yu]

Sir. Eb is inversely proportional to Ia. Or directly..???

[@iticlassroom9511]

Maja aa gya sir ji

[@manikantasaragadam1751]

Armature current and back emf are inversly proportional not directly proportional

[@rajanikantsingh3160]

confusing Ia is directly proportional to Eb or inverly????😵‍💫

[@_.animeworld._]

Inversely as it is -Ea

[@rjrabby7485]

when the back EMF is increased in a motor, the armature current tends to decrease.then was the in 15.00 minute was correct?

[@simranmalhotra9653]

Totally amazing

[@bikash3003]

why ac motor is not self regulating ?back emf is also present threre ...

[@ashutoshkumar8636]

Sir bhut deri se lecture aata hai apka

[@girishsutar1]

Nice Sir

[@vikashmourya8622]

Overload condition should be also discussed...

[@mohammadanowarhossain8699]

I think there is a mistake. Ia is not directly proportional to Eb as increasing Eb will decrease the armature current Ia.

[@anuragfunde1569]

Ia will be inversely proportional to Eb

[@skgolamhassanali1289]

Thanks sir🤗🤗

[@imSurajsingh24]

You Break hard concepts in easy way ❤️❤️❤️

[@scaryminati5528]

Sir EMF equation ka video nhi dikh raha sir

[@rockingroky876]

Sir Va-Eb isme Eb is more than Ia wil b less and if En is less Ia value will b high according to eqn but apne proportional bola ki samajme ny aya

[@puppylovers1073]

Perfect

[@hassusaifi595]

Hello Ranjan sir Case -2 Me load dalne k baad agr Eb km hoga to current bhi to km hoga Jb tk Eb nhi bdega to Ia kese bdega. Please daut clear kre.

[@karunakarmishra4615]

Jab ld denge to -Eb cum hoga, tab Vt-Eb/Ra ka value badhega. Is tarah Ia ka value badhega. Aur jab load cum karenge to vice-versa effect hoga.

[@nandalalsingh7178]

Thank you sir....

[@JackMillerIndia]

armature current must be inversely proportional to back emf

[@NIGHTSHADE123]

Ia should be inversly proportional to Eb🤔🤔🤔🤔

[@SAKSHISINGH-hq9gk]

thanx a lot sir

[@IM-Imran007]

Can someone give me an answer that y we don't use the concept of back EMF in AC machines ? or this Back EMF is generated in both DC motors and generators or only DC motors ?

[@amishra1503yb]

Back emf is generated only in DC motors

[@piyakshidebnath7326]

Sir agar ia directly proportional hai Eb ke sath toh jab ia decrease hota hai tab toh eb increase rehta hai ?? Then how it's directly proportional ??

[@bilalhassan5289]

thanks

[@nazrealam203]

Sir aap bich rasta me chor ke chal jate h sir continue rakhiye sir plz
