Question

an ammeter has 10 divisions graduated between 0 and 0.5 m ampere what is the least count of ammeter​

Answer 1

Answer:

0.05 mA

Explanation:

Least count =

$\frac{reading}{total \: division}$

So least count =

$\frac{0.5}{10} = 0.05m \: ampere$

Hope you understand it!!!!

Answer 2

Answer:

Given: 50 VSD ≡ 49 MSD 

Hence , 1 VSD =5049 MSD 

Least count of the instrument =MSD−VSD=2(1−5049) 

( ∵ MSD is given as 2 mm )

Hence, least count of vernier calipers =2(501)=251 mm
