shunt

Physics

An electrical resistor or other element connected in parallel with some other circuit or device, to take part of the current passing through it. For example, a shunt is used across the terminals of a galvanometer to increase the current that can pass through the system. A shunt-wound electric generator or motor is one in which the field winding is in parallel with the armature circuit. In a series-wound electrical machine the field coils and the armature circuit are in series.

Electronics and Electrical Engineering

1. In general, a term for parallel.
2. (instrument shunt) A resistor, usually of a relatively low value, that is connected in parallel with a measuring instrument, such as a galvanometer. Only a fraction of the current in the main circuit passes through the instrument so that the shunt increases the range of the instrument and also protects it from possible damage caused by current surges. See also universal shunt.
