Here's the solution to the questions: a) A permanent magnet moving coil instrument has an internal resistance of 100 \, and requires a current of 1 \, mA to reach the full scale deflection (f.s.d.). Determine i) The value of the shunt resistor necessary to extend the range to 500 \, mA Step 1: Identify the given values. Internal resistance of the meter, R_m = 100 \, . Full scale deflection current of the meter, I_m = 1 \, mA = 0.001 \, A. Desired full scale current, $I =
