How to calculate least count of ammeter
Web26 feb. 2024 · Explanation: Circuit a: Both batteries are in series so total valtage is 15V Circuit sries restnace is 2 ohms So Current I= V R = 15 2 =7.5A Voltage drop across top 1 ohm resistors = I ⋅ R =7.5V, right side being +ve So Voltmeter reads +7.5 -6 V ==+1.5V Circuit b: The 9V and 6 V sources oppose, so resultant voltage is only 3V instead of 15V. Web11. Take at least four set of observations in the same way by changing the value of R in steps. 12. Record your observations. 07 08 Calculations 1. Calculation for X 1.

Did you know?
Web3 okt. 2024 · Hence it’s least count is 10 V/25 divisions =0.4 V/division, meaning as least as 0.4 Volts can be measured using this voltmeter. Similarly for the shown ammeter least count can be calculated as 50 A/25 divisions=2A/division and hence as least as 2 Amperes can be measured using it. WebTo convert it into a 10 A ammeter, the galvanometer coil should have a (A) 0.01 resistor connected across it (B) 0.02 ... If the least count of the voltmeter is 0.1V, the number of divisions on its scale is (A) 90 (B) 91 (C) 100 (D) none. Q.51 In …
WebVoltmeters can be used to measure the voltage drop across a single component or supply, or they can be used to measure the sum of voltage drops across two or more points or components within a circuit. For example, if we connect a voltmeter across the terminals of a fully-charged automobile battery, it will indicate 12.6 volts. Web14 apr. 2024 · There are two knobs on the instrument- “Adj” and “Gain”. With “Adj”, position of the needle on the ammeter is adjusted. The knob “Gain” is used to increase the sensitivity of the instrument. Increase the micrometer setting till the anode current in the ammeter shows a maximum. Note down the micrometer reading.
WebMathematically 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 … Web30 aug. 2024 · Least count of a measuring instrument is the least value of physical quantity that can be measured accurately using the instrument. Take a spring balance whose range is 0-25kg. Measurement=1kg. Number of divisions=10. Least count=1/10 =0.1kg or 100g.
Web10 apr. 2024 · So, Least Count of Voltmeter is 0.4 V and Least count for Ammeter is 0.02 A An ammeter has a range of 0-3 ampere and there are 30 divisions on its scales. What is its least count? How to determine the least count of a spectrometer? To determine the Least Count of that Circular Vernier Scale. the principle is similar to that of the linear ...
WebFind the least count of a milliammeter in which there are 20 divisions between 400mA and 500mA Medium Solution Verified by Toppr Least count= No. of divisionsRange if a ammeter from 400mA to 500mA, and it has 20 divisions in total on the scale, then its least count is 20100mA=5mA ∴ Least count of milliammeter is 5mA.
