Question

Define the least count of an instrument.

Answer 1

Answer:

The smallest value that can be measured by the measuring instrument is called its least count.

Answer 2

Least count

Explanation:

Least count indicates the degree of precision of an instrument. It is the smallest measurement that can be taken accurately with the measuring instrument. Example: A Vernier scale on a caliper may have a least count of 0.1 millimeters or 0.01 micrometers. Least count is the smallest change in the value that can be captured by the measuring instrument. The least count error occurs with both systematic and random errors.
