A resistor arrangement for measuring current strength having connection elements and a resistor element between the connection elements. The connection elements and the resistor element are arranged in a plane and in a row such that the arrangement is strip-shaped and has its smallest spatial extent perpendicular to the current direction. The resistor element has two contact sides and the connection elements each have a contact face connected to the contact sides. When current flows through the arrangement, current flow lines are formed which are deflected at at least one of the contact sides by an angle of at least 5° at the transition from the connection element to the resistor element.
A resistor arrangement for measuring the strength of an electric current flowing through the resistor arrangement, the resistor arrangement comprising at least two strip- or plate-shaped connection elements for connecting the resistor arrangement to an external circuit and at least one strip- or plate-shaped resistor element arranged between the connection elements with respect to the direction of the current, the connection elements and the resistor element for forming the resistor arrangement being arranged in a plane next to each other and in a row with respect to each other in such a way that the resistor arrangement has the form of a strip and has its smallest spatial extent in a direction oriented perpendicular to the direction of the electric current, the at least one resistor element consisting of a material of which the electrical resistivity at room temperature is greater by at least a factor of 10 than the electrical resistivity of the material of the connection elements, the at least one resistor element having two contact sides parallel to each other, and the connection elements, each having a contact face at which they are connected to one of the contact sides of the at least one resistor element or of a further resistor element and are in electrical contact, wherein the at least one resistor element is arranged in such a way that, when current flows through the resistor arrangement, current flow lines are formed which are deflected at at least one of the contact sides of the resistor element by an angle of at least 5°, averaged over the entire contact face, at the transition from the connection element to the resistor element, this deflection taking place in a plane which is perpendicular to the direction of the smallest spatial extent of the resistor arrangement.
