Conversion of Galvanometer into Ammeter

Product Code : SCL-PLE-11740

Quick Answer: The Conversion of Galvanometer into Ammeter apparatus is a workstation with a sensitive moving-coil galvanometer, a low-resistance shunt unit and a regulated DC supply, for converting the galvanometer into an ammeter of a chosen range.

Last updated: 18 October 2026

Key Features

  • High-sensitivity moving-coil galvanometer.
  • Low-resistance shunt unit to connect in parallel with the meter.
  • Regulated DC source for the experiment.
  • Shows how a shunt extends a meter’s current range.

How It Is Used

Students first find the galvanometer’s resistance and full-scale current, then calculate the shunt needed for the required range and connect it in parallel with the meter. Comparing readings against a standard ammeter checks the conversion and shows how current divides between the meter and the shunt.

Frequently Asked Questions

How is the shunt calculated for the Conversion of Galvanometer into Ammeter apparatus?

The shunt S equals G × Ig / (I − Ig), where G is the galvanometer resistance, Ig its full-scale current and I the required range.
