The basic sensitivity of a meter might be, for instance, 100 microamperes full scale (with a voltage drop of, say, 50 millivolts at full current). Such meters are often calibrated to read some other quantity that can be converted to a current of that magnitude.
The current sensitivity of the galvanometer is defined as the ratio of deflection produced in the galvanometer to the current flowing through it. Mathematically, the current sensitivity of the galvanometer is given as S i = θ / I = = n B A / k.
The sensitivity of a galvanometer is higher if the instrument shows a larger deflection for a small value of current. Sensitivity is of two types, namely, current sensitivity and voltage sensitivity. Current Sensitivity ; The deflection θ per unit current I is known as current sensitivity θ/I. θ/I = nAB/k. Voltage Sensitivity

The current sensitivity of a galvanometer is the deflection per unit current produced by the galvanometer. A high-sensitivity galvanometer can be used to measure very low values of currents. A low-sensitivity galvanometer can be used to measure high values of currents. Created by Mahesh Shenoy.
