Sensitivity of a galvanometer is defined as the ratio of deflection in the galvanometer to the unit change in unknown resistance. The sensitivity of a galvanometer can be increased by increasing the number of turns, increasing the coil area, or using a strong magnet.

Definition of sensitivity of a galvanometer:
The sensitivity of a galvanometer is defined as the ratio of the deflection in the galvanometer to the unit change in the unknown resistance.
Explanation:
A galvanometer is an instrument used for detecting and measuring small electric currents. It consists of a coil of wire suspended in a magnetic field. When a current flows through the coil, it experiences a torque that causes it to rotate. The amount of rotation is proportional to the strength of the current.
The sensitivity of a galvanometer is a measure of how responsive it is to changes in the current. A more sensitive galvanometer will produce a greater deflection for a given change in the current.
The sensitivity of a galvanometer is determined by its construction and the strength of the magnetic field. It is usually expressed in terms of the number of divisions of the scale that correspond to a given change in the current.
Mathematically, the sensitivity of a galvanometer is given by the formula:
Sensitivity = Deflection in the galvanometer / Unit change in the unknown resistance
Where the deflection in the galvanometer is measured in divisions of the scale and the unit change in the unknown resistance is measured in ohms.
Conclusion:
The sensitivity of a galvanometer is an important parameter that determines its usefulness for measuring small currents. A more sensitive galvanometer is preferred for accurate measurements.
