A slip ring arrangement for feeding electrical current to, or receiving electrical current from, coil windings which are mounted on a rotatable shaft for rotation therewith, the slip ring arrangement comprising a first slip ring of electrically conducting material which is substantially cylindrical and which is mounted on the rotatable shaft, adjacent one end of the rotatable shaft, for rotation therewith; and a second slip ring of electrically conducting material which is electrically isolated from the first slip ring, which is substantially flat, and which is mounted on the said one end of the rotatable shaft for rotation therewith. Suitable for use with alternators. Allows reduction in length of slip ring arrangement and rotatable shaft. The second slip ring reduces wear on its contacting brush.
