To solve the problem of determining the resistance of the shunt used in the ammeter, we can follow these steps: ### Step 1: Understand the Given Information - Maximum current (I_max) = 2.0 A - Current for full-scale deflection of the coil (I_g) = 1 mA = 0.001 A - Resistance of the coil (R_g) = 25 Ω ### Step 2: Calculate the Current through the Shunt ...
