Web5 de abr. de 2024 · We know that for the conversion of a galvanometer into a voltmeter, a high resistance is required. So, if the resistance of the galvanometer is G and that of the high resistance is R, when they are connected in series, the total resistance of the arrangement becomes the following: RSeries = G + R. Now, the galvanometer behaves … Web14 de mai. de 2024 · Artwork: An ammeter (A) is a sensitive instrument that measures only relatively small currents. If you want to measure bigger currents, you need to divert a high proportion of them around a "shunt" resistor (Ω). Since the meter and the shunt are in parallel, they have the same voltage across them.
