Question
Define the term ‘current sensitivity’ of a moving coil galvanometer.
Advertisements
Solution 1
The current sensitivity of a galvanometer is defined as the deflection produced in the galvanometer when a unit current flows through it.
Mathematically, it can be given by:
IS = `(NBA)/k`
Where k is the couple per unit twist.
Solution 2
Current sensitivity is defined as the deflection e per unit current.
