Question

derive an expression for the deflection shown by the pointer of moving coil galvanometer in terms of current being passed through it ,no. of turns of the coil and the magnetic field.​

Answer 1

Answer:

By current sensitivity

I=KΦ/NBA

Where I=current

K=torsional constant

Φ=deflection

N=no.of turns of coil

B=magnetic field

A=area of coil
