Measurement of Current with a Voltage DAQ
... An electrical shunt is a device that passes current around a point in a circuit via a low-resistance path. It has many possible applications, such as an ammeter shunt that allows an ammeter to indirectly measure current that is too large for it to measure directly. This type of shunt is a resistor w ...

Current source
A current source is an electronic circuit that delivers or absorbs an electric current which is independent of the voltage across it.A current source is the dual of a voltage source. The term constant-current 'sink' is sometimes used for sources fed from a negative voltage supply. Figure 1 shows the schematic symbol for an ideal current source, driving a resistor load. There are two types - an independent current source (or sink) delivers a constant current. A dependent current source delivers a current which is proportional to some other voltage or current in the circuit.
