Abstract
A shunt is composed of multiple pieces with at least some of the pieces being connected by a conductive channel that provides uniform flow of current. The conductive channel may be a recess, raised portion, stand-alone component, or other channel that directs current to flow from one piece of the shunt to another piece in a uniform manner, resulting in an accurate current reading for the shunt. Further, the shunt may include multiple pieces that are composed of different materials.
