Question

plz tell me how to find least count of voltmeter or ammeter during experiments.

Answer 1

First tell me its first observation and zero error
No of event also
But by taking example we see that
If it has no zero error then we divede the first unit with no of cuts between zero and that first unit
Ex-5/10 means 5 is first observation and 10 cuts between zero and 5 hence least count is 0.2
If there is zero error then it depends on how much errors there

Answer 2

If it is given from 0-3 there are 9 divisons , then divide 9/3 do we will get 3 . This is the method to find the least count
