What is least count of micrometre?
0.01 mm
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 least count of Milliammeter?
Find Least count of Ammeter and Voltmeter given below
Voltmeter | Ammeter |
---|---|
For Voltmeter, We see that 10 Divisions is equal to 5 Volts So, Least Count = 5/10 = 0.5 V | For Ammeter, We see that 10 Divisions is equal to 100 Milli Amperes So, Least Count = 100/10 mA = 10 mA = 10 × 10 -3 A = 10 -2 A = 0.01 A |
What is the least count of voltmeter?
0
A voltmeter has a least count of 0.
What is least count of scale?
Least count of a measuring instrument is the smallest measurement that can be made accurately with the given measuring instrument. A metre scale normally has graduations at 1 mm (or 0.1 cm) spacing, as the smallest division on its scale.
What is least count of height gauge?
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 least count of pressure gauge?
Pressure which is measured in minimum of perticular pressure gauge called its least counts. Suppose in a pressure gauge range 0-6 is devided in to equally 6 parts for each 1 kg/sq cm and 1 parts devided in to itself by 10 division for each 1 kg/sq cm.
What is the least count of galvanometer?
There is no least count to a galvanometer as it does not depict any quantity.
Which instrument has minimum least count?
Hint: Least Count of an instrument is the smallest change or value of a physical parameter an instrument can measure or detect. So, the screw gauge has minimum least count.
What is the least count of a measuring instrument?
The smallest value that can be measured by the measuring instrument is called its least count. Measured values are good only up to this value. The least count error is the error associated with the resolution of the instrument.
What is the least count of a meter scale?
The least count of an instrument is the smallest measurement that can be taken accurately with it. The least count of meter scale is 1mm, and that of the ammeter shown below is 2 ampere. In daily life, the length is measured with the help of a meter scale. It is graduated in cm and mm such that the value of one small division is 1 mm.
What is the least count on a vernier caliper?
The smallest reading which can be accurately measured with a vernier caliper is called its least count (L.C),it is also known as vernier constant. It is the difference between one main scale division which is 1 mm and one vernier division which is (0.9) .
How to measure the least count of the instrument?
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.
