    I am a repeater, who was never able to clear the concept of potentiometer in two years of coaching. But then this video by Alakh sir is the best way to clear the concept. Hit like if u agree....
    For the last potentiometer problem, I took the cells in parallel by mistake. But I got the same answer as Alakh sir got in series.
    Then I found out that the answer will be same for the cases, which I verified by changing the value of any one of the cells and calculated the value of X by parallel and series combination, which gave same answer in both the cases......

    • @dipankar7074
      @dipankar7074 5 лет назад +5

      Yes I also mistakenly solve the problem by parallel combination and the answer comes out to be E=8 V and x= 3.33

    • @krishnamnagar4045
      @krishnamnagar4045 4 года назад +7

      I think you might have already got an answer after 5 months but if not then...
      The cells are already in parallel combination if you see closely. The 0V(coming from 40V battery) potential would be carried forward to both the cells and their potential will also be 0V. At the galvanometer side, the cells again meet so the potential will be the same there too. The current will not flow in this circuit when placed at 3.33m.
      What Alakh sir did is, he separated that part from the whole circuit and then passed a current of 1A(unlike us). After that, he found the potential difference coming out to be 8V and put it in the formula.
