Question

factors on which voltage sensitivity depends

Answer 1

Answer with Explanation:

Sensitivity of galvanometer:A galvanometer is said to be sensitive when it gives large deflection when small current is passed through  it or small voltage applied across it.

Voltage sensitivity of galvanometer:It is defined as the deflection produced in the galvanometer when a unit voltage is  applied across  two terminals.

Voltage sensitivity=

Where N=Number of turns

A=Area of coil

B=Magnetic field produced in coil

K=Torsion constant of galvanometer

R=Resistance of galvanometer

Voltage sensitivity of a moving coil galvanometer is directly proportional to area of coil.

It is inversely proportional to torsion constant of galvanometer coil

It is directly proportional to magnetic field .
