Shunt FAQ – term origins and definitions

DC Ammeter shunt – The term DC ammeter shunt stems from one of the early uses of the devices as a means of measuring DC currents in a circuit utilizing a simple analog milli-volt meter.  Many of the terms associated with these products are directly related to this...

Shunts ; Measuring current taken to a higher level

Precision shunts are very precise resistors inserted into a circuit in order to measure the current flowing through that circuit.  The shunt does this by providing a very small voltage drop across its resistance proportional to the current flowing through the shunt. ...
