Formula for calculating least count of vernier scale?

Answer 1

hey ! hi

iam gonna tell you how to find the least count of a vernier scale.

first of all lc is the least possible measurement made by an apparatus this stand as a symbol of its accuracy

now coincide the 0 of main scale to that of vernier scale

if n main scale divisions = m verneier scale divisons

then 1 vsd = n/m msd

then lc = 1msd - 1 vsd (if n>m)

= 1 vsd - 1 msd (if n<m)
