The least count error is the error associated with the resolution of the instrument. If we use a metre scale for measurement of length, it may have The distance through which the screw advances when the circular scale of screw gauge is rotated through only one division is called least count Least count of screw gauge =1/100 mm = 0.01 mm. Least Count of screw gauge = Pitch of screw gauge / No. Least count of screw gauge =1/100 mm = 0.01 mm Diameter = Divisions on circular scale least count + main scale reading = 52 0.01 + 0 = 0.52 mm Diameter = 0.052 cm. So, option (b) is correct. Q. The pitch of the screw gauge is 0.5 mm and there are 100 divisions on its circular scale. The minimum length that can be measured using a screw gauge is known as the least count of that screw gauge. Lets assume a screw gauge with the least count of 0.01 mm. 0. of divisions on circular division. For screw gauge, the count should be less than 0.01mm. By the way, we can also use the circle scale or gauge pitch of the screw to measure it. Least Count of Screw Gauge The main scale has 10 divisions to a centimetre. Suggest Corrections. A screw gauge has least count of 0.01mm and there are 50 divisions in its circular scale. Least Count of the Screw Gauge The Least count (LC) is the distance moved by the tip of the screw, when the screw is turned through 1 division of t 0.005 cm. Least Count of the Screw Gauge The Least count (LC) is the distance moved by the tip of the screw, when the screw is turned through 1 division of t Least count of the micrometer screw gauge = 0.01 mm. 01 mm Hence, the least count of Similarly, some screw gauges have a 1mm pitch with 100 divisions on the circular Therefore, the least count of any screw gauge is 10 - 3 cm. = 0.52 mm. least count of screw guage = pitch of screw gauge total number of divisions of circular scale Leat count of screw gauge = 1 mm 100 = 0. The smallest division on the main scale is 1 mm, which equals the pitch (p) of the screw gauge. The smallest reading up to which a screw gauge can be measured is called least count of screw gauge. It can be find out by following method; L.C = Micrometer Screw gauge: Definition, least count & Applications Micrometer screw gauge is an instrument used to measure the diameter of thin wires, the thickness of small sheets of glass, What is its total reading? Thus, Solution: The main scale reading is 2.5 mm and the circular scale reading is 38. By substituting the values in the formula, we get. x Least Count = 16 + What is the L.C. of screw gauge? Least Count is a measure of Accuracy of the Instrument. The smallest reading , measurable using a screw gauge (also called micrometer) is called least count (L.C) of screw gauge. It can be find out by following method; L.C = pitch of screw gauge no. of divisions on circular scale. LC = 1 100 = 10 - 3 cm. The least count of a screw gauge is 100th of a millimeter or 0.001 mm Hi, Screw Guage is a device which is used to measure diameter of thickness of small sheets of glass,thin wires,plastic etc. It can measure upto 1/1 Now, in order to calculate the diameter of the wire, we are given: $L.C = 0.01 mm$ Measured The least count is the smallest unit of measurement which an instrument can take accurately. The least count of screw guage can be determined by th Main scale reading = 1.6 cm = 16 mm Circular scale reading = 48 Shown reading = M.S.R. a screw gauge has least count of 0 01 mm and there A screw gauge has least count of 0.01 mm and there are 50 divisions in its circular scale. Solution : least count of instrument = 1 main scale division 1 vernier scale division L. C = 0.5 m m 49 50 ( 0.5 m m) = 0.01 mm Screw Gauge (or Micrometer Screw) In general vernier Hold the object whose dimensions is to be measured between the anvil and spindle of micrometer screw gauge with gentle pressure. Note down the main scale reading just before zero of a circular scale. This is called the main scale reading (M.S.R.) Note down the number of circular scale division (n) which coincides with the main scale line. Hi, Screw Guage is a device which is used to measure diameter of thickness of small sheets of glass,thin wires,plastic etc. It can measure upto 1/1 The least count is the smallest unit of measurement which an instrument can take accurately. For screw gauge, the count should be less than 0.01mm. By the way, we can also use the circle scale or gauge pitch of the screw to measure it. gauges have different accuracies. they are called micrometers, not screw gauges. some can attain accuracy much greater than 1/10 mm, so the answer below is not true. Diameter = Divisions on circular scale least count + main scale reading = 52 0.01 + 0. Solution Verified by Toppr Correct option is C) As the he number of divisions on main scale are 10 to a centimeter, so the smallest division on main scale will be 1mm and it will be the pitch (p) The pitch of the screw gauge is: NEET 2020 0.01 + C.S.R. The least count of screw-gauge is 0.01 means it is 100 times more accurate than a meter scale. Similarly, some screw gauges have a 1mm pitch with 100 Answer.
