An inherently balanced electrical supply system for a bus (202) provides improved reliability for bus termination in computer systems. The apparatus includes a single current source (212) that is fed into a feeder line (216, 218) connected to opposite ends of the bus (202) at about the midpoint of the feeder line, dividing the path into two equal-length segments (216, 218). Integrated circuit chips (208) connected to the bus, when switched on, draw esentially equal amounts of current through each feeder segment, creating substantially equal voltage drops at each end of the bus.
