How to Evaluate Rsh of PMMC based Ammeter?

Rsh of PMMC based Ammeter evaluator uses Shunt Resistance = (Meter Current*Meter Resistance)/(Electric Current-Meter Current) to evaluate the Shunt Resistance, The Rsh of PMMC based Ammeter formula is defined as the shunt resistance connected in parallel with the PMMC meter movement. This shunt resistor allows the ammeter to measure higher currents than the PMMC meter movement alone can handle by diverting a significant portion of the current around the delicate meter movement. Shunt Resistance is denoted by R_sh symbol.
