description The invention relates to a current measuring apparatus for redundant measurement of an electric current (I) with a low-resistance current measuring resistor (1) for current measurement according to the four-lead technique and with a magnetic field sensor (14). The invention provides that the electric current (I) to be measured in the current measuring apparatus is divided into a main current path with a main current (11) and a secondary current path with a secondary current (12), the main current path and the secondary current path together forming a parallel circuit. The low-resistance current measuring resistor (1) is arranged in the main current path and has the main current (11) flowing through it, while the magnetic field sensor (14) is arranged in the secondary current path and measures the secondary current (12).
