In a given ammeter, a student observes that the needle indicates 17 divisions in the ammeter when performing an experiment to verifY Ohm.s law. If the ammeter has 10 divisions between o and 0.5 A, then what is the value of 17 divisions?

Answer»

Solution :Since the ammeter has 10 divisionsbetween 0 and 0.5 A, its least COUNT or value of 1 DIVISION `=(0.5A)/10 =0.05A`
Therefore, the value of 17 DIVISIONS
`=17(0.05A) =0.85A`
