is it only me or sometimes physics problems feels so surreal like man how can we visualise infinite resistances in all three directions! even tough its not possible its wild to think about it and its result comes what a simple "3r/8"

Why current is I/6+I/6 If current is coming from one branch then same current will come other end too then why I/3 and not I/6 5:40

[@PHYSICSSIRJEE]

Time stamp of your doubt?

[@soundsinteresting208]

@@PHYSICSSIRJEE sir 5:40

[@PHYSICSSIRJEE]

I/6 is with only current pumped in... Imagine current as water pumped into this pipeline network... Situation -1 is only pumping in of water at A without any pump at B... So water spreads as I/6... Now situation -2 is a case where water is already filled and you are pulling water from B using a straw without doing anything at A. Then I/6 flows. Now superposition of situations 1 and 2 is applying push simultaneously at A and a pull at B... Total I/3 will flow. That's what superposition means. A battery between A and B is visualised as superposition of situations 1 and 2

[@redgeronimo1]

​@@PHYSICSSIRJEEsir, but how is it physically possible to pass current I only through A? one sided batteries don't exist, so there must be somewhere that the other terminal is connected to?

[@mr.rachetphilanthrophist601]

​@@redgeronimo1that is what i don't understand too, maybe negative terminal is somewhere other than from where we are extracting out

How to find R_AB in 13:35

[@PHYSICSSIRJEE]

You cannot find it using JEE skills, if you use the wrong method by taking extra symmetry that's not there, you will get R/3 but it's wrong... So the idea is, you can tell the third statement at 13:35 is definitely false without solving it

sir 14:04 how is the second stmt false?

[@pratyushsingh1211]

Pump I in B and the current I/8 flows through all 8 directions now..in the wire connected to B and in the exact east direction...the wire meets a junction node which is connected to C, one node in the front and another one below it...However observe the path taken to come to C or the node below...It is symmetrical with respect to B but the node in the front isnt ( we take a turn from the junction node to go to C or the node below, but to go to the front node...we move forward which is a different path..not similar to the other two...hence their potentials will be different ( potential at C and the node below will be same and different from potential at the front node) hence since potentials are different...and resistances are same ..therefore the current will not be distributed equally in the three nodes from the junction...to calculate such potentials and equivalent resistances...search on internet and read the articles on an answer on electrical engineering stack exchange..I doubt though, you will be able to understand them..Quite high level mathematics...I skipped them..lol
