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)
LC= Value of one main scale division Total number of divisions on vernier
0.1 mm
where on the vernier caliper would you read to obtain the vernier scale reading
We need two readings. One is Main scale reading and the other is vernier scale reading. Main scale reading will be read on the main scale. We need an indicator to read it. Right? The marking ie zero of the vernier is that indicator. So the reading on the main scale which has been just crossed by zero of the vernier is taken as Main scale reading. Now to get VSR, we need vernier scale coincidence. How do we get this? Any one of the divisions of the vernier will be found coincided with some divisions marked on the main scale. We don't worry about that main scale division but we concentrate only on the vernier scale division. This is VSC This VSC is to be multiplied by least count. So VSC x LC gives the VSR Now MSR + VSR gives the accurate reading.
No unit for vernier scale coincidence. But as we multiply it by least count which has unit then we get vernier scale reading with the same unit. Of course main scale reading and vernier scale reading would have the same unit
1)Main Scale is fixed(It does not move) Vernier scale slides along main scale.2)Least count of Mainscale is 0.1cmLeast count of vernier scale is 0.01cm
Vernier scale consists of main scale and vernier scale. The first line or the zeroth line coinciding with the main scale reading is the main scale reading. The vernier line except zeroth line coinciding with any line on main scale is the main scale reading.
Their Vernier scale consists of two readings; the Vernier scale and the main scale. One can read that by the first line is the main scale and the next line is the Vernier reading.
