Abstract
A current measurement circuit suitable for measuring the flow of current along a path in an electrical circuit such as a part of an electric power assisted steering system comprises a current measurement resistor that is located in series in the electrical path through which a current to be measured may flow, a first measurement sub-circuit that measures the voltage dropped across at least a part of the resistor and produces a first output signal, and a second measurement sub-circuit that measures the voltage dropped across at least a part of the resistor and produces a second output signal, and in which the electrical connections of the two sub-circuits to the resistor are independent of each other.
