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.
