Product Code : SCL-EELE-12304
Indian Lab Suppliers supplies the Conversion of Galvanometer into an Ammeter (G to A) with Power Supply and 2 meters (C.R.) (Product ID: 12304) as part of its electronics engineering lab equipment range. It covers measuring a galvanometer’s resistance and figure of merit and converting it into an ammeter.
Quick Answer
After finding the galvanometer resistance G by half deflection and its figure of merit, students connect a low-value shunt S = IgG/(I − Ig) in parallel to make an ammeter of range I, where Ig is the full-scale galvanometer current. The converted ammeter is calibrated against a 0-50 mA DC milliammeter (65 mm rectangular), with current set by the potentiometer from a 5 V DC, 50 mA IC-regulated supply. The galvanometer reads 30-0-30 on a 65 mm rectangular dial. The board is self-contained.
