Doubt Forum
Индия
Добавлен 18 апр 2020
Doubt Forum is an endeavor to create a platform where intermediate to advanced level of problems on Physics and Mathematics are explained in a unique style- 'concept to solution', wherein approximately half of the content in a video lesson is dedicated to learning associated concepts, definitions and theories and in the remaining half, the actual solution of the problem is demonstrated utilizing the concepts just learnt.
We have adopted this 'concept to solution' approach with a view to not just enable students to solve questions of the similar nature, but also to empower them to solve unprecedented problems which they may come across in a competitive examination.
Doubt Forum is an evolving and interactive platform where viewers can submit problems/topics of their interest as 'comments' and we would provide explanation of the concept along with solution. We would also welcome suggestions to make the content richer, more effective and beneficial.
Let us start learning together!

15 ohm because in upper formation 2 r are in series and then they become parallel to each other and then every one us in series
thank , keep going<<
Areh pseudo aspirants kya 15 ohm laga rakha hai, answer sir ka sahi hai. We have to find equivalent resistance across AB potential. Kabhi copy bhi khol liya karo kaam ayega.!
