sir is it always necessary to take an vernier scale reading if 0 of the vernier scale is precisely coinciding with the main scale then also we have to apply the formula to calculate the final reading...

@AllLabExperiments Жыл бұрын

Just take vernier scale reading to be zero and make the table accordingly. Although formula will also give the reading same as the main scale reading but for the sake of making ur observation table, do it.

@AllLabExperiments 3 жыл бұрын

Just look at the main scale... Choose an interval like between 260 and 265 degree marks there are 10 divisions then each division is half of a degree.
