Cbse Class 11 Physics Practical Viva Questions [VERIFIED]

A: The least count (LC) is the smallest measurement that can be accurately read. For a standard Vernier Caliper, LC = 1 Main Scale Division (MSD) – 1 Vernier Scale Division (VSD). Typically, 1 MSD = 1 mm, and 10 VSD = 9 MSD, hence LC = 1 mm – 0.9 mm = 0.1 mm or 0.01 cm .

The reading an instrument shows when it should ideally read zero (e.g., when jaws of a calliper are closed). Cbse Class 11 Physics Practical Viva Questions
