Thank you sir. Was search in a search of detailed explanation like this.

[@ashokmyla7395]

Good lectures comes from only good heart sir

[@mamatha_999_9]

@12:20 the values of L1 & L2 are same??
For L2 i think it is d21 d22....
Please clarify sir...

[@daviduday1790]

yes, it will be d21 d22...

Thank you sir very nice explanation

[@lecturesinelectricaleng]

You're most welcome

Very good lecture Sir. Thanks 🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏

[@pavanambala9594]

as usual excellent lecture sir

[@aniketgangwar3867]

Sir how can be use equation 2 directly in composite conductor case as we derived eq 2 by the assumption that sum of current is zero wheras in composite case the sum of current in each conductor is I not 0
Time at 8:57

[@aniketgangwar3867]

@@lecturesinelectricaleng but sir how eq 2 applicable for a same phase conductor whose sum of current is not zero

[@sujathakondala8237]

Sir at 13:40 in the video as you said every strand in the conductor is in parallel so for effective inductance we can directly solve and get it know sir what is the use of taking avg and then dividing by x and solving....?!

[@sureshkondru3154]

Heartfully thank you sir..

[@Papyrususer]

Sir, why did you include the flux lines beyond conductor 1 that is, the flux lines at point P?

[@Papyrususer]

Surely, the flux lines linking conductor 1 are between d12 and (d12+2r1). I don't understand why we are considering till the point P.

[@kousikmullapudi5126]

Sir the lecture is awesome ..but only one doubt on d12.you are saying that flux is not linking with the conductor 1 and again why do you take distance between 1,2 and I didn't understand the terminology what you have said about d12

[@kousikmullapudi5126]

3:25 sir

[@kumkumsinghal8875]

@@lecturesinelectricaleng sir this is what i m not getting that why did u not include the flux produced between d12 distance
sir i have watched lecture 9,10 as u said but still i didn't get
sir plzz clear my doubt

[@053_abdulhannanbhat8]

Sir at 11:26 you write inductance due to strand 1= lamda1/(i/x), but sir my question is the flux that is linking is because of current through conductor 1 and also rest of the current through other conductors so how come we divide lamda1 by i/x which is the current through strand 1 to get the inductance of strand 1

[@electricalengineeringvideo6595]

Sir, Did you forget to write currents I1 and I2 in equations lambda1p1 and lambda_1p2 respectively at 3:39? please respond sir

[@tuhinsardar6749]

Thank you sir 😊😊

[@balajiyadavpassimpalli7814]

Hello sir, (@10:25)
When we multiply 1/x inside.... it'll become xth root...
lly, when we multiply 1/y inside .... it'll become yth root...
then why are we putting yth root in the numerator...
as the first term is x..???

[@dr.tirupathirajukanumuri4451]

I have derived correctly only. It is correct only. Please check

[@rajpurohitnikita7248]

Sir, what is the difference between loop inductance and inductance?

[@rajpurohitnikita7248]

Sir i would request you to upload videos as per MAKAUT syllabus for EE students...MAKAUT is a university in WB with lots of Engineering colleges under it...a large number of students are now at their homes without books due to covid issues...we all had left our hostels in a rush and didn't bring any...if u refer to the syllabus in makaut website and make a playlist on different subjects...you will surely attract and help a lot of students...❤️

[@sankhamitra3862]

Sir have you taught transients in power system topic already or you will teach this topic in future??

[@SuperAstha]

Sir, this Lambda_1 is the flux linkage due self as well as mutual flux(due to current in wire 2 strands). Yet, to calculate L1, you are dividing lambda_1 by I/x. But if we consider mutual flux due wire 2 then to calculate L1(total inductance due self and mutual flux), the flux linkage due strands in wire 1 should be divided by I/x and mutual flux linkage due to current in wire 2 strands should divided by I/y. Please help me with this. Thanks

Please tell what is the answer

[@abhinavpushkarna3143]

Is there any difference between horizontal spacing and vertical spacing of conductor?
