In a Vernier caliper, \(N+1\) divisions of vernier scale coincide with \(N\) divisions of main scale. If 1 MSD represents 0.1 mm, the vernier constant (in cm) is:
Calculating the Vernier Constant (V.C.)
Step 1: Formula for the Vernier Constant (V.C.)
The Vernier constant is given by:
V.C. = Value of 1 MSD − Value of 1 VSD
Step 2: Relate MSD and VSD values
If (N + 1) VSDs coincide with N MSDs, then:
Value of 1 VSD = Value of 1 MSD × (N / (N + 1))
Step 3: Substitute Values and Simplify
Now substitute the values:
V.C. = 0.1mm − 0.1mm × (N / (N + 1))
V.C. = 0.1 / (N + 1) mm
Quick Tip
To convert to centimeters, use:
V.C. = 1 / 100(N + 1) cm
The Vernier constant is given by:
V.C. = Value of 1 MSD − Value of 1 VSD
If (N + 1) VSDs coincide with N MSDs, then:
Value of 1 VSD = Value of 1 MSD × (N / (N + 1))
Now substitute the values:
V.C. = 0.1mm − 0.1mm × (N / (N + 1))
V.C. = 0.1 / (N + 1) mm
To convert to centimeters, use:
V.C. = 1 / 100(N + 1) cm
