To convert a galvanometer into an ammeter with a range of 0-5 A, we need to calculate the shunt resistance that should be connected in parallel with the galvanometer. Here’s a step-by-step solution: ### Step 1: Identify the given values - Resistance of the galvanometer, \( R_G = 75 \, \Omega \) - Full-scale deflection current of the galvanometer, \( I_G = 5 \, \text{mA} = 5 \times 10^{-3} \, \text{A} \) - Desired maximum current for the ammeter, \( I = 5 \, \text{A} \) ### Step 2: Use the formula for shunt resistance ...
