Question

Give expression of current sensitivity

Answer 1

Answer:

Refer to the attachment given

Answer 2

Answer:

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
