How to Evaluate Time Constant of Moving Iron Ammeter?

Time Constant of Moving Iron Ammeter evaluator uses Time Constant = Shunt Inductance/Shunt Resistance to evaluate the Time Constant, The Time Constant of Moving Iron Ammeter formula is defined as the characteristic time it takes for the ammeter's pointer to reach a certain fraction (typically 63.2%) of its final deflection when subjected to a step change in current. It represents the speed at which the ammeter responds to changes in current and settles to its final reading. Time Constant is denoted by T symbol.
