To convert a galvanometer into an ammeter, we need to connect a shunt resistor in parallel with the galvanometer. Let's go through the steps to find the required shunt resistance. ### Step-by-Step Solution: 1. **Identify the Given Values**: - Resistance of the galvanometer (G) = 50 ohms - Maximum current through the galvanometer (Ig) = 0.002 A - Desired maximum current through the ammeter (I) = 0.5 A ...
