Current resistors are electronic components that have obtained enormous influence in daily life though we mostly do not recognize such truth. Resistors are installed in cars, TVs, laptops, mobiles and all other assets that are based on current. Therefore we are in contact with resistors daily although without recognizing.

Resistors are mostly utilized to limit current, to install a fixed potential, to transform electric energy to heat and consequently luminescence. However they might also be utilized to calculate potential or currents.

The primitve resistors had been utilized only for standard functions. Needs as to power usage were not existent. The trends in design of electronic components as well as the technical advancement of other components challenge current resistor producers continuously. Hence resistors are developed further continuesly. The necessity for tinier devices using less energy on the one hand and increasing needs on the other hand, supported the advancement of specialized power resistors like low ohm resistors.

Low ohm resistors are mostly used for precision current sensing. Resistors utilized for measurement are classified shunts. They are installed in the circuit in which they should calculate the currents. Since Ohm's law tells there will be a potential on the power meter shunt showing the current.
Low ohmic shunts contain low ohm resistors that detect even the smallest current exactly. E.g. those high precision resistors are utilized in electric products to calculate critical charge and discharge cycles.

They are produced in a variety of arrangements. The most universal type is the electrical SMD resistor. Those are surface mounted devices that are attached on the frame. Instead Hybrid mounting resistors are mounted in different ways.

Apart from way those shunts are installed they are placed on a circuit frame that will be a standard part of an electronic device. They might be utilized as BMS batterymangement system to charge the celular akku we use or in an infrared receiver enabling us to use remote control of our television. In either case they support the standard of comfort we have.
