Abstract: A thick film current sensing resistor (10) is provided having an input terminal (14) for receiving an electrical current (I), and an output terminal (16) for outputting the electrical current (I). A film of resistive material (20) extends between the input and output terminals (14 and 16) and is electrically coupled to the input and output terminals (14 and 16) so that current (I) flows through the film of resistive material (20). A pair of sensing terminals (24 and 26) are provided to sense a voltage potential (Vs) across the film of resistive material (20). The sensed voltage (Vs) provides an indication of the current (I). An gap (32) is formed in the film of resistive material (20) between the input and output terminals (14 and 16) and the sensing terminals (24 and 26). The length (L A ) of the gap (32) defines a voltage sensing point of the sensing terminals (24 and 26).
