SUMMARY
The conversion of a galvanometer to an ammeter involves connecting a shunt resistance in parallel, allowing most of the current to bypass the galvanometer while a small portion is measured. This method enables accurate measurement of high currents without the need for a dedicated high-range ammeter. The shunt resistance is typically much smaller than the galvanometer's resistance, allowing for precise calculations of total current based on the measured value. The discussion clarifies that while the range of an ammeter can be increased using different shunt resistances, it cannot be decreased for a specific ammeter model.
