To solve the problem, we need to find the resistance of the ammeter formed by converting the galvanometer with a shunt resistor. Here's the step-by-step solution: ### Step 1: Identify Given Values - Resistance of the galvanometer, \( R_G = 40 \, \Omega \) - Full-scale deflection current of the galvanometer, \( I_G = 2 \, \text{mA} = 0.002 \, \text{A} \) - The new range of the ammeter is 6 times the previous value, so: \[ I_{max} = 6 \times I_G = 6 \times 0.002 \, \text{A} = 0.012 \, \text{A} = 12 \, \text{mA} ...
