Abstract
The invention relates to a current sensor which works with a toroidal body, through which at least one conductor to be evaluated is extended and from which a measuring signal is taken. The toroidal body (1) comprises a magnetostrictive material and conductor runs (2) of length-dependent resistance material are applied over at least one ring region of the toroidal body (1). The resistance changes of the conductor runs are evaluated to determine a value representative of the current (I) to be measured.
