The full-scale current is known to be 1.0 mA, but the galvanometer resistance must be measured. Voltmeter The galvanometer, by itself, is also not a very effective voltmeter because its resistance is too low to approximate the infinite resistance of an ideal voltmeter. The small range is also inhibitive. flow in sand

"WebThe conversion of a galvanometer into an ammeter is done by attaching a low resistance parallel to it. This is called “shunt” or “S.”. The range of this newly-formed ammeter depends upon the shunt resistance values or S. Consider a circuit in which a resistance R and shunt S are connected in parallel combination with a voltage source. " - How can a galvanometer be used as a voltmeter
