Instrument Shunt

Instrument shunts are devices used in electrical and electronic properties measuring and testing instruments to measure current. They are typically used in conjunction with ammeters to divert a portion of the current being measured, allowing for accurate measurement of high currents.

Instrument shunts are designed to have a known resistance value, which is used to calculate the current flowing through the circuit. By measuring the voltage drop across the shunt, the current can be determined using Ohm's law (I = V/R).

These shunts are commonly used in various applications, such as power distribution systems, electrical testing laboratories, and industrial equipment. They are essential for accurate current measurement in high-current circuits, where direct measurement with an ammeter may not be feasible.

In summary, instrument shunts are important components in electrical and electronic properties measuring and testing instruments, allowing for accurate measurement of high currents by diverting a portion of the current through a known resistance.
