Sensitivity of a galvanometer

  1. Feb 9, 2007 #1
    1. The problem statement, all variables and given/known data
    1) A capacitor of capacity 3 micro farad charged by a potential of 2 volt when discharged through a Ballistic galvanometer gives a deflection of 24 divisions. Determine the sensitivity of the Ballistic galvanometer.

    2. Relevant equations

    3. The attempt at a solution

    The solution as given in my book is as follows:
    Charge (Q) =Capacity x Potential difference
    = 6 micro coulomb
    Sensitivity= deflection/charge
    = 24/6
    = 4 division/coulomb
    My question is: Isn’t sensitivity = charge/deflection?

    If you make it charge/deflection then a device which shows no deflection whatsoever no matter how high the charge has infinite sensitivity. :smile:
