Abstract: A current measuring arrangement includes a first electrical conductor having a first resistance and a second electrical conductor switched in parallel and having a second, higher resistance, wherein both the first resistance and the second resistance are each below 0.1Ω. The arrangement further includes a hall sensor, which is prepared to measure a current through the second electrical conductor, and a calculation unit, which is connected to the hall sensor and which is designed to calculate a total current through the first electrical conductor and the second electrical conductor based on the current measured by the hall sensor. A switching device provides a comparable functionality.
