Abstract

This article proposes the transformation of a microampermeter into a milliampermeter using a nichrome wire resistor at the external terminals of the microampermeter, thereby enabling the same instrument to measure currents with differences in the order of 10-3A, and providing an instrument with a scale ranging from milliampers to microampers.
