The power factor (p.f) of a pure capacitive circuit will be 1, because in capacitive circuits, capacitors are used, which minimizes the value of reactive power almost equal to zero .

Thus the ammeter can be arranged to have different ranges by merely having a different number of turns on the coil. Since the coil carries the whole of the current to be measured, it has a few turns of thick wire. The usual ranges obtained by this method are from 0 -250 A.
