m of Moving Iron Ammeter

Go Multiplying Power = (Rm/Rsh)*sqrt((1+((Omega*Inductance)/Rm)^2)/(1+((Omega*Shunt Inductance)/Rsh)^2))

Rsh of PMMC based Ammeter

Go Resistance of Shunt = (Full Scale Deflection Current*Internal Resistance of Meter Movement)/(Current-Full Scale Deflection Current)

Resistance at switch position 'n' for multi range Ammeter

Go Resistance at nth Switch Position = (Resistance at Switch Position 1+Internal Resistance of Meter Movement)/Nth Multiplying Factor

Nth resistance in multi-range Ammeter

Go Nth Multiplier Resistance = Internal Resistance of Meter Movement/(Nth Multiplying Factor-1)

Microammeter Current

Go Microammeter Current = Electric Potential Difference/Volume Resistance of Insulation

m of PMMC based Ammeter

Go Multiplying Power = 1+(Internal Resistance of Meter Movement/Resistance of Shunt)

Current at Full-scale reading

Go Current at Full-Scale Reading = Full-Scale Voltage Reading/Resistance of Meter

Time Constant of Moving Iron Ammeter

Go Time Constant = Shunt Inductance/Rsh

Average Meter Current

Go Average Current = Electric Current*0.637

Peak Meter Current

Go Electric Current = Average Current/0.637

Nth resistance in multi-range Ammeter Formula
