This application relates to methods and apparatus for sensing current in a monitored current path, where the monitored current path is bidirectional such that current can flow in either direction along the monitored current path. A current sensor has first and second sense resistors () configured to each pass a current corresponding to the current in the monitored current path. The first and second sense resistors are configured to have a matching arrangement, such that current flow through the first sense resistor when current is flowing in one direction in the monitored current path matches current flow through the second sense resistor when current is flowing in the opposite direction in the monitored current path.
