Question
Define current sensitivity of a galvanometer.
Advertisements
Solution
Current sensitivity of a galvanometer is defined as the deflection produced in the galvanometer when a unit current flows through it.
θ = `("nBA")/"k""I"`
So, for a given value of I, θ will be large if `("nBA")/"k"` is large i.e n, B and A should be large and k should be small.
