The least count of an instrument is the smallest measurement that can be taken accurately Vernier callipers, an instrument for making very accurate linear. Vernier caliper least count formula is calculated by dividing smallest reading of main scale with total number of divisions of vernier scale. Least Count plays an important role in measurement devices like Vernier Caliper. This blog explains the procedure of calculating the least count of the metric.

The main scale is graduated is centimeter while Vernier scale slides along the main scale and is graduated in veernier less than the millimeter. The least count error is the error associated with the resolution of the instrument.

## Least count

Leas least count error occurs with both systematic and random errors. Least count of the main scale: A Vernier scale on caliper may have a least count of 0. This Blog is Taggged: We can learn about the use of V. Vernier caliper is an instrument used to measure the length, diameter, radius etc. Use a magnifying glass if necessary.

Measured values are good only up to this value. Count the number calliepr divisions on the Vernier scale.

## Use of Vernier Calipers

The least count of measuring device plays an important role for measurement. From Wikipedia, the free encyclopedia.

When the jaws of Vernier calipers are brought into contact, the zero of the Vernier must coincide with the zero of the main scale. For example, a sundial may only have scale marks representing the hours of daylight; it leaxt have a least count of one hour.

Your email address will not be published. The smallest value that oof be measured by the measuring instrument is called its least count. The jaws A and B are fixed where B and D are moveable. If the zero of the Vernier scale is to the left of the zero of the main scale then the error is negative. Difference between potentiometer and voltmeter in tabular form. How to find Vernier caliper least count formula?

The lower jaws A and B are used to measure length.

### How to calculate the least count of the metric vernier caliper ?

Since the least count of the Vernier caliper is 0. Least count error [ edit ] The smallest value that can be measured by the measuring instrument is called its least count.

LC of vernier caliper is the difference between one smallest reading of main scale and one smallest reading of vernier scale which is 0. This page was last edited on 30 Decemberat Comments Created By Friedenwald, ; page 1. Least count uncertainty leadt one of the sources of experimental error in measurements.

Instruments of higher precision can reduce the least count error. The least count as the name suggests is the finest measurement you can take with the help of that Vernier calipers. Ir ;ve also always had an interest in making games. Since the zero error is negative, the zero correction will be positive.

Zip lock Bag 8 x 10 cm – Pack of By repeating the observations and taking the arithmetic mean of the result, the mean value would be very close to the true value of the measured callipwr. The upper jaws C and D are used to measure the internal diameter of objects like a hollow cylinder or tube.

Number of divisions on Vernier scale: Learn how your comment data is processed. Vernier caliper least count formula is calculated by dividing smallest reading of main scale with total number of divisions of vernier laest.

Divide 1 cm into that much number of divisions; the value obtained is the least count of the main scale in cm. Retrieved from ” https: How to calculate the least count of the metric vernier caliper? In vernkerthe least count of a measuring instrument is the smallest change in the measured quantity that can be resolved on the instrument’s scale.
