Current measuring resistors (also known as
shunt resistors ) are essential components for the precise measurement of electrical currents. Due to their low resistance value, they make it possible to determine the current based on the voltage drop according to
Ohm's law These resistors are used in numerous areas, including industry, medical technology and automotive engineering. They are used for current monitoring in batteries, power supply units and motor controls as well as for energy and power monitoring in intelligent measuring systems.
Depending on the area of application, a distinction is made between
on-board and
off-board current measuring resistors. On-board resistors are integrated directly into electronic systems, while off-board resistors are mounted externally to safely measure higher currents and efficiently dissipate heat.
