Question

In a given ammeter, a student sees that needle indicates 17 divisions in ammeter while performing an experiment to verify Ohm's law. If ammeter has 10 divisions between 0 and 0.5 A, then what is the value corresponding to 17 divisions?

Answer 1

An ammeter has 10 divisions between 0 to 0.5 A. So

1 division = 0.5 A/10

17 divisions = 17/0 = 0.85 A
