Question

How to calculate least count of voltmeter and ammeter?

Answer 1

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.
