Web7 de nov. de 2015 · Galvanometers can be used to make voltmeters. The needle of a galvanometer moves in response to current, but if we know the resistance of the coil, then we can use Ohm’s law to determine the … WebThe galvanometer can also be used as a voltmeter to measure the voltage across a given section of the circuit. For this it must be connected in parallel with that section of the circuit. Further, it must draw a very small current, otherwise the voltage measurement will disturb the original set up by an amount which is very large. Usually we ...
