The current sensitivity of a moving coil galvanometer depends on

Question

The current sensitivity of a moving coil galvanometer depends on (A) the number of turns in the coil (B) moment of inertia of the coil (C) current sent through galvanometer (D) eddy current in Al frame

Tardigrade Admin · Accepted Answer

Current sensitivity =(nBA/K) where K is constant of torsional rigidity. B is the magnetic field A is coil area.

Q. The current sensitivity of a moving coil galvanometer depends on

the number of turns in the coil

moment of inertia of the coil

current sent through galvanometer

eddy current in Al frame

Current sensitivity $= \frac{n B A}{K}$
where K is constant of torsional rigidity.
B is the magnetic field A is coil area.

Current sensitivity =KnBA​ where K is constant of torsional rigidity. B is the magnetic field A is coil area.

Current sensitivity $= \frac{n B A}{K}$
where K is constant of torsional rigidity.
B is the magnetic field A is coil area.
