To convert a galvanometer into an ammeter, we need to add a shunt resistor in parallel with the galvanometer. Here's a step-by-step solution to the problem: ### Step 1: Understand the given values - Resistance of the galvanometer (G) = 120 Ω - Full-scale deflection current of the galvanometer (Ig) = 5 mA = 5 × 10^(-3) A - Desired maximum current range of the ammeter (I) = 5 A ### Step 2: Calculate the current through the shunt resistor ...
