pls. tell me what is the meaning of current senitivity of a galvanometer.....
i mean if the current sensitivity of a galvanometer is 10mm/μA then what does it mean?

Let's say the current sensitivity of a galvanometer is 10mm/μA and 1μA current flows through that galvanometer then the deflection of the galvanometer would be 1μA *10mm/μA=10mm

i know that the galvanometer shows defelection for current but here it shows 10mm .........what does it mean???????????

i got this problem when i was studying abt wheatstone bridge

pls. Help!!!!!!!

It means that for every 1uA increase in current, the needle moves 10mm.

but what i knows is that galvanometer shows reading through angular defelection.......so how can it defelect by 10mm??????????

" what does it mean " It means 1μ A is flowing through the galvanometer.
