What is the least count of meter?
The least count error is the error associated with the resolution of the instrument. A metre ruler may have graduations at 1 mm division scale spacing or interval. A Vernier scale on a caliper may have a least count of 0.1 mm while a micrometer may have a least count of 0.01 mm.
How do you find the least count?
Mathematically a measurement instrument Least Count is calculated by dividing main scale reading by the total number of divisions on the main scale. And if the instrument also has a Secondary scale. Then instrument LC is the ratio of main scale L.C. and number of divisions on the secondary scale.
How do you find the least count of a meter scale?
The least count will be the same unit of the magnitude of one division. So correspondingly we can alter the unit of least count into the required unit. Least count of metre scale can be written as, \[0.1cm\] or \[1mm\] according to our requirement.
What is least count of simple scale?
Units and Measurement 0.001m or 0.1 cm is the least count of a simple scale.
What is least count of cell?
Least Count – definition least count of meter rule is up to 1 mm. least count of Vernier caliper is 0.01 cm.
What is the least count of a 30 cm scale?
The length of an object was measured to be 30 cm by a linear scale of least count 0.1 cm.
What is the least count of Centimetre scale?
0.1 cm
The least count is the ratio of main scale reading to the number of divisions on main or secondary scale. For example, the main scale reading of the vernier caliper is 1 cm and the total number of divisions on the main scale is 10. Hence, the least count for the main scale of the vernier caliper is 0.1 cm.
How to calculate the least count of an instrument?
General Least Count Formula. Here is how you can calculate least count of an instrument having a single scale. Formula: 1. Least Count = Value of 1 main scale division / Total main scale divisions. Least count formula for an instrument. Here is the least count formula for an instrument having a secondary scale along with the main scale.
How to calculate the least count of micrometer?
It is calculated by dividing the main scale reading (1 cm) by the number of divisions of the main scale (10). Least Count of Mechanical Vernier Caliper is 0.02 mm. Because it can measure a minimum 0.02 mm dimension. How to calculate Least Count of Micrometer?
Which is the least count of an ammeter?
An ammeter has a range of 0-3 ampere and there are 30 divisions on its scales. What is its least count? So, Least Count of Ammeter is 0.1 A
How to calculate the least count of a ruler?
Least Count Of Secondary Scale = Value of 1 secondary scale division / Total secondary scale divisions Least Count of an instrument = Least count of primary scale / Total secondary scale divisions We can calculate least count of ruler using formula 1 mentioned before.
