Claim:
A high-power resistor comprising a plurality of resistor elements ( 1 ) made of sheets of an electrically conductive resistance material, each resistor element having first ( 13 ) and second ( 14 ) terminals, and said resistor elements being mutually separated by ring-shaped insulating first shims ( 2 ), a first terminal of a first resistor element of the plurality of resistor elements being connected to a first terminal of an adjacent second resistor element of the plurality of elements, and a second terminal of the second resistor element being connected to a second terminal of an adjacent third resistor element of the plurality of resistor elements, thus forming a current path of serially connected resistor elements, wherein each of the resistor elements is formed as a ring with an outer element diameter and an inner element diameter, split by a continuous radial slit ( 12 ), and wherein said first and second terminals of each resistor element are arranged adjacent to the silt therein on both sides thereof, said first shims ( 2 ) each extending in a plane and comprising a plurality of radially-extending channels ( 22 , 23 ) providing radially-extending flow paths for a cooling medium which are contained between two adjacent resistor elements and which, via gaps (01, 02, 03, 04), communicate with a cylinder-shaped space (SP 1 ), limited in a radial direction by inner edges of the resistor elements and said first shims, respectively, and with a space (SP 2 ) located in a radial direction outside outer edges of the resistor elements and the first shims, respectively.
