Question

sensitivity of MCG and derive it's formula also ​

Answer 1

The sensitivity (i.e. current sensitivity) of a galvanometer is defined as the angle of deflection per unit current flowing through it.

I=knABθ I = k n A B θ where θ is the angle of deflection , N is its turns, A is area, B is magnetic induction & k is the couple per unit twist.

$\huge\star\mathfrak\red{{Answer:-}}$

the deflection of coil of MCG changes by an amount of d 0 when current ( I) through it changes by an amount ,(dI )

si=d0/dI
