Question

least count of ammeter

Answer 1

The least count of any measuring tool is the minimum reading or value that can be measured by it. Hence, 0.5 Volts is the least count for this Voltmeter. Now what if the meter is a digitalvoltmeter or the multimeter that we generally use nowadays. So, how to find its least count.

Answer 2

Hey.


Here is the answer .


_____________________________


Least count : Least count is the smallest value which we can measure by using a particular measuring instrument.


We can find it by dividing the meters range from its divisions.



Ammeter : An ammeter is an instrument which measures the current in a circuit.



Least count of ammeter = The highest reading of the ammeter / total no. of divisions.


eg.- If an ammeter range is 0 to 100mA and ammeter has 20 divisons.

Then its least count will = 100mA/20 =5mA.
