Introduction
Monitoring current flow in electrical and electromechanical systems is commonly used to provide feedback to improve system operation, accelerate fault detection and diagnosis, and raise efficiency. A current monitoring circuit usually involves placing a sense resistor in series with the monitored conductor and determining the voltage across the sense resistor. To minimize power loss in the sense resistor it is kept as small as possible, resulting ...
