Least count of a Vernier scale is calculated using the following formula, Least count = Smallest reading on main scaleNumber of divisions on Vernier scale=1mm10 = This is the least count for Vernier Callipers. Hence, the least count for Vernier Callipers is 0.1mm.
What is the value of least count error?
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 .
What is the value of least count?
The least count of an instrument is defined as the least or minimum value which the instrument can measure with precision . The value of the least count gives the information that which instrument should be used to measure a particular length or directly measurable physical quantity.
What is least count give example?
In the simplest manner, we can define the least count of an instrument as the minimum value that we can measure from it. For example, the smallest distance that we can measure from a meter scale is 1mm , therefore the least count of meter scale is 1mm.
What is the value of least count of metre scale?
A metre scale normally has graduations at 1 mm (or 0.1 cm) spacing, as the smallest division on its scale. You cannot measure lengths with this scale with accuracy better than 1mm (or 0.1 cm).
What is LC of vernier caliper?
The LC of vernier calliper is the difference between one smallest main scale reading and one smallest vernier scale reading of 0.1 mm 0r 0.01 cm. ... The Least Count measuring instrument is determined mathematically by calculating the main scale reading by the cumulative number of divisions on the main scale.
What is height gauge least count?
The graduated scale has least count of 0.02 mm like Vernier Caliper has. And the way of taking a reading of measurement in Vernier Height Gauge is same as in Vernier gauge.
What is percent error?
Percent error is determined by the difference between the exact value and the approximate value of a quantity , divided by the exact value and then multiplied by 100 to represent it as a percentage of the exact value. Percent error = |Approximate value – Exact Value|/Exact value * 100.
What is the value of zero error?
Its zero correction is (take L.C. = 0.01 cm) Hint: When the zero on the main scale does not coincide with the zero on the Vernier scale then it is known as Zero error for Vernier. ... The smallest value the Verner can measure is known as Least count.
What is least count error with example?
Least Count Error – definition
The least count error is the error associated with the resolution of the instrument . Example: During Searle’s experiment, zero of the Vernier scale lies between 3. 20×10−2m and 3.
What is the least count answer?
Define least count. Answer: The smallest value up to which an instrument can measure is called least count. For example least count of meter rule is up to 1 mm and least count of Vernier caliper is 0.01 cm .
What is least count of balance?
1% = 0.01 mg least count balance. It shows that if you have a balance with least count 0.01 mg, you can weigh minimum 10 mg sample on it. Other weights can be calculated accordingly. Update: Simply you can calculate the minimum limit by multiplying least count by 1000.
What is the least count of a micrometer *?
Least count of the micrometer screw gauge = Pitch of screw / No. of circular scale division = 0.1 mm / 100 = 0.001 mm. Hence the least count of the micrometer screw gauge is 0,001 mm .
What is least count of CM scale?
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 .
What is least count of simple scale?
Units and Measurement
What is the least count of simple scale? 0.001m or 0.1 cm is the least count of a simple scale.
What is the least count of 30 cm scale?
The length of an object was measured to be 30 cm by a linear scale of least count 0.1 cm .
