Question

You are given four ammeters A, B, C and D having least counts mentioned below: (I) Ammeter A with least count 0.25 A. (II) Ammeter B with least count 0.5 A. (III) Ammeter C with least count 0.05 A. (IV) Ammeter D with least count 0.1 AWhich of the ammeters would you prefer for doing an experiment to determine the equivalent resistance of two resistances most accurately, when connected in parallel?​

Answer 1

Answer:

The ammeter which will give more accurate answer must have the lowest least count possible. So the ammeter with least count 0.05 A should be preferred for doing the above experiment
