FAQs on How to Read Vernier Calliper Video Lecture - Physics for JEE Main & Advanced

1. How do you read a Vernier caliper?
Ans. To read a Vernier caliper, first, note the main scale reading that lines up with the zero mark on the Vernier scale. Then, find which Vernier scale division aligns perfectly with a division on the main scale. Add the main scale reading to the Vernier scale division that aligns to get the final measurement.
2. What is the least count of a Vernier caliper?
Ans. The least count of a Vernier caliper is the smallest measurement that can be read on the scale. It is calculated by dividing the smallest division on the main scale by the total number of divisions on the Vernier scale.
3. How can Vernier calipers be used to measure internal dimensions?
Ans. To measure internal dimensions using Vernier calipers, the inside jaws of the caliper are placed inside the object to be measured. The depth probe is then used to measure the internal depth of the object, giving an accurate measurement.
4. What are some common mistakes to avoid when using a Vernier caliper?
Ans. Some common mistakes to avoid when using a Vernier caliper include not ensuring the jaws are clean and well-aligned, misreading the Vernier scale, applying excessive force when taking measurements, and not zeroing the caliper before use.
5. Can Vernier calipers be used to measure depth?
Ans. Yes, Vernier calipers can be used to measure depth by using the depth probe on the bottom of the caliper. The depth probe is used to measure the depth of the object, providing an accurate reading for depth measurements.
