Question

An ammeter has a range of 0-3 ampere and there are 30 divisions in its scale. calculated the least count of the ammeter

Answer 1

Least count =Range / total no. of divisions
= 3/30 = 0.1 A.
Thus, the least count of the ammeter is 0.1 Ampere.

Answer 2

least count=range/total divisions

=3/30

=1/10

=0.1A

hope it helps.....
