SUMMARY
The sensitivity of a Ballistic galvanometer is determined by the formula Sensitivity = deflection/charge. In this case, a capacitor with a capacity of 3 microfarads charged to 2 volts discharges a total charge of 6 microcoulombs, resulting in a deflection of 24 divisions. Therefore, the sensitivity is calculated as 4 divisions per coulomb. The discussion clarifies that sensitivity is not defined as charge divided by deflection, as this would incorrectly imply infinite sensitivity for devices with no deflection.
