All voltmeters and ammeters have scale starting from zero to 100 or you may consider any value.
Let suppose scale is 0 10 20 30 40 50 60….100 Amps
Now to get least count just see the number of divisions between 0 and first scale that is 10 and if there are 10 division then divide first number 10 by numbet of division you will gey the least cou t that is one similary if tthre are 20 di isions then leadt count is 0.5.
I hope you got the concept.
Least count - Least count is a smallest value which you can measures.
How we find it in ammeter and voltmeter -
We can find it by dividing the meters range from its divisions.
For example - If a ammeter range is 0 to 200mA and ammeter has 20 divisons.
Then its least count will = 200mA/20 =10mA.
