How did the exam go ??

[@YashDeshmukh]

@@okipullup8382 Hey! Thanks for asking! Couldn't clear it in the May 2019 attempt but then finally cleared it in the Dec 2019 attempt! 😄

same! same!, its 8.30AM now, exam at 10.30AM, i don't think i will clear either!!

Seven years later and this video I came across still helped me with just one simple explanation. Thank you very much, sir!

[@VarunSharma-v3n]

Sir ur videos are truly a masterpiece

[@ALLABOUTELECTRONICS]

Do let me know your questions and suggestions here.

[@thephysicsholic580]

Sir with all due respect do you know what a proof means? I'm sorry to say this but what you have done is similar to 2+3 = 5 then 2= 5-3 so then again 2+3=5 hence proved

[@sanathkumar68]

Sir you have said that we are going to prove star to delta conversion and first u have took three equations top of that heading is delta to star and after sometime heading has been changed to star to delta we are confused by that sir

Explain with logic. The way u r teaching seems illogical.

Sir in exam it's asked for 10 marks,i think it's not enough derivation for 10 marls

As per calculation, Rbc = 40 ohm. Please check once again.

[@mightygod-bw3cn]

So on 4:01 to 4:20 you converted ( y to Delta) configuration is that right? My question asked assume you have a Y configuration of resistors where each resistor in Y has a value of 60 ohms convert the Y to delta configuration

[@rakshithp8110]

That mean, in exam if they ask to 'prove star to delta conversion' , first i should do delta to star, later with those equations i should prove star to delta... Am i correct?? Or can i write delta to star expression in first ( like W.K.T ) and can i prove star to delta further?? Please answer me..

Which one is used for step up transformer star to delta or delta to star

[@sudarshansinha]

Awesome explanaton . Thank You so much .

[@mangosushii_.]

thank you teacher!

[@sansudhar1]

why it is necessary to equate the delta with star for delta to star conversion. And why adding and subtracting the equation in delta to star? It is like memorising the steps. will you elaborate?

[@sansudhar1]

similarly why we multiplying the equations of delta to star equations for getting star to delta equation?

[@ALLABOUTELECTRONICS]

Dear Sudharsan, As both DELTA and STAR networks, are equivalent network so we can perform all these operations. (Multiplying and equating etc.). If you still feel it's just mathematical steps, then what I would suggest you find the current at each node in both the networks. And as both the networks are the equivalent network, so current at each node will be same. So, you can equate them. And from there also you will get the same equation for the conversion. I hope, it will clear your doubt.

explanation was good

[@narasimhareddyvemireddy3395]

Sir doubt at adding eq 4 5 6 How the square terms of Rab Rbc and Rac goes. Can u explain that

[@ALLABOUTELECTRONICS]

when you add equation 4, 5, and 6, Rab Rbc and Rac will be common in all three terms, If you just take them out (i.e Rab*Rbc*Rac) then you will have (Rab +Rbc+Rac)*(Rab*Rbc*Rac) Please pause a video at 5:47 and look for a while, you will be able to get it.

[@narasimhareddyvemireddy3395]

Sir Rab^2 Rbc^2 Rca^2 is common but u have taken only Rab and Rbc Rca

[@ALLABOUTELECTRONICS]

Please check carefully, only Rab*Rbc*Rac will be common. Each term has one only one square term (e.g Rab^2*Rbc*Rac +Rab*Rbc^2*Rac +Rab*Rbc*Rac^2) So, only Rab*Rbc*Rac will be common.
