Science Practical (C10)

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 0.5A, then what is the value corresponding to 17 divisions?

Answer

An ammeter has 10 divisions between 0 to 0.5 A.

So,

1 Division = 0.5 A / 10 = 1/20

17 divisions = 17/20 = 0.85 A
