Question

What is the smallest reading of the vernier caliper?

Answer 1

1. The smallest reading that a vernier calliper can measure is called the least count.
2. The value of the least count can be calculated by dividing the least count of the main scale by the number of divisions on the vernier scale.
3. The least count of the main scale is o.1 cm. In most of the vernier callipers, the number of divisions is 10. Therefore the least count of the vernier calliper is

L.C = 0.1/10 = 0.01 cm

4. Therefore the smallest reading that can be measured using a vernier calliper is 0.01 cm.
