Meter shunts are usually precision
Web26 feb. 2024 · The current through the shunt generates a voltage drop that is measured. The current value is derived from Ohm’s law and the known resistance ( I = V / R ). To keep power loss – and thus heat development – to a minimum, shunts must have resistive values no higher than the milliohm range. Some are even below that. http://www.mwftr.com/netw1/06%20dArsonval.pdf
