    'r' should be used for internal resistance and not R in the table
    r=(l1-l2)R /l2

      @salmaelsayed4251 7 ปีที่แล้ว +1

      It should be connected after them. Remember it this way: the -ve of Galvanometer is always connected to the jockey, and the jockey is always last, so the galvanometer will definitely be connected after them to be at the end with the jockey. Good Luck :)

    • @chandrapandey822
      @chandrapandey822 7 ปีที่แล้ว +10

      aman saxena
      Sure my friend, consider the following points:
      1.) Your score in practical depends on a lot of factors:
      a.) Your School/Your relationship with your teachers:
      If your school is ummm.... kinda not very strict(thats very common though)and your subject teacher sees you in a bit high regard(generally{not always} for top 5 students in the class) then thats a big plus factor.
      b.) Your preboards score( if you screwed you boards practical)
      c.) Luck: It depends on the examiner if he/she is strict then bye bye 30 but mostly they are quite chilled out( cant say for sure).
      2.) My advice to you will be start studying 1week prior to the practical and watch edunovus practical videos. These videos are 5-30 min each and spending 2-3 hours everyday will be fine.
      3.) Chem is mostly rote learning but in physics make sure that you know the circuit diagrams of the corresponding experiment trust me it helps a lot in setups during exams.
      Setting up connections on metre bridge or junction diode will be a pain in the ass if you are not familiar with circuit diagrams so learn them by heart.
      4.) Study Semiconductors/Optics/Electricity chapters thoroughly for viva.
      5.) Learn each and every graph of every chapter.
      6.) Do not,I repeat do not argue with your examiner, he can ruin your marks if he can.
      7.) Get your practical file checked and covered ( brown)
      8.) Relax dude it ain't no tough if you know you'll score 85-90% in boards then its 99% that you will get a 30
      Thats my advice...
      Your welcome
