    It is worth noting that the equivalent resistance between nodes 1 and 2 is 7/12*R. I calculated this using the node voltage method in circuit analysis. How can I share a document containing the solution?

    There are multiple methods to solve these kinds of questions either by symmetry, plain old Kirchhoff law or my personal favourite I draw a simplified version of this circuit kind of in 2d by checking the connectivity of each of these resistors hardly takes a minute and then we can find some symmetry in them

    Hi professor ,
    I'm asking you a question it's sensible.
    Do you support this book 📙 " Brief Answers to the Big Questions
    Book by Stephen Hawking "
    I'm very supportive on this 😁

    Sir, if a particle performs SHM, even the value of its displacement from the mean position (x) also performs SHM, Can the same be said for the values of velocity (v) and acceleration (a) of the particle?

      And equivalent resistance between 1 and 3 ?
      In these points there are no symmetry like points 1 and 7 .
      Here current distribution is difficult so I asked you

      Watch all my 94 MIT course lectures. Start with 8.01, then 8.02, then 8.03. Do all the homework and take all my exams. *I guarantee you that you will then do very well on the Physics portion of any freshman college or JEE exam* You will find all information you need on this channel in three playlists "Homework, Exam, Solutions & Lecture Notes".
      8.01 & 8.02 will each take about 200 hours, 8.03 about 250 hours.
