Magnetic measurements: Introduction, measurement of flux/ flux density, magnetizing force and leakage factor. WebWhat are shunts and multipliers? Shunts and Multipliers. Amp meters can be used to measure different current ranges, to do this the meter must have a shunt resistor fitted in parallel with the measuring circuit. Where Rs is the shunt resistor, Rm is the meters internal resistance and n is the multiplier (Current to be Measured). novelkeys cherry sand
