(N/A) The least count of an instrument is the smallest measurement that can be accurately measured by it.
When we use an instrument with a smaller least count,the absolute error in the measurement is reduced.
Since the relative error (or percentage error) is directly proportional to the absolute error,a smaller least count leads to a smaller percentage error.
Therefore,using an instrument with the smallest possible least count increases the precision and accuracy of the measurement.
