Ampere 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.

The formula to determine the shunt resistor for an ampere meter is as follows:

Rs = Rm / (n - 1)

Where Rs is the shunt resistor, Rm is the meters internal resistance and n is the multiplier (Current to be Measured).
