Question

CURRENT SENTIVITY FORMULA

Answer 1

Answer:

Current sensitivity of a galvanometer is defined as deflection per unit current, ϕ I = NAB k Here, ϕ is the angular deflection, k is the torsional constant of the spring, and NAB is the magnetic torque per unit current produced in the galvanomet

Explanation:

Answer 2

Explanation:

The sensitivity (i.e. current sensitivity) of a galvanometer is defined as the angle of deflection per unit current flowing through it. `I=k/(nAB)theta` 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
