Homework Statement


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.



Homework Equations





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:
