Question

The radius of a thin wire is measured by ________

Answer 1

The radius of a thin wire is measured by an instrument called a “screw gauge”.

It is used for the measurement of small quantities like diameter of a wire due to its small least count.

Least count is the minimum value an instrument can measure.

The least count of a screw gauge is 0.01 mm.

This value is very small and is accurate when measuring the diameter of a wire.
