Question

Define Current Sensitivity.

Answer 1

Current Sensitivity : It is defined as the deflection produced in the galvanometer, when unit current flows through it.

$I_s=\frac{\theta}{I}=\frac{N A B}{k} .$

The unit of current sensitivity is $\operatorname{rad} \mathrm{A}^{-1}$ or $\operatorname{div} \mathrm{A}^{-1}$.
