A shunt is a low-ohm resistor that can be used to measure current. … The entire current flows through the shunt and generates a voltage drop, which is then is measured. Using Ohm’s law and the known resistance, this measurement can then be used to calculate the current (I = V/R). The term shunt is used in filter and similar circuits with a ladder topology to refer to the components connected between the line and common. The term is used in this context to distinguish the shunt components connected between the signal and return lines from the components connected in series along the signal line. More generally, the term shunt can be used for a component connected in parallel with another. For instance, shunt m-derived half section is a common filter s…
