6) Application:

Shunt resistors are often used in cases where currents need to be measured. They can be found in multimeters, as terminating resistors on current transformer or as a separate measurement accessories. When using a combination of an appropriate shunt and an external multimeter set at voltage range, large currents can be measured, or combined with an oscilloscope, current wave forms can be made visible.

The name "shunt" originates from the fact that galvano and moving-iron meters only can handle limited currents. And to be able to measure larger currents a significantly part of the current is bypassed via a resistor. A shunt therefore is a common resistor named after it's purpose.
