Abstract
An electronic open-circuit current measuring circuit is configured to measure a current delivered between a current source and a load during an open circuit condition. The electronic open-circuit current measuring circuit includes an electronic voltage drop component electrically connected between a first buffer output and an electrical voltage difference calculating circuit. The voltage drop component is configured to reduce a first voltage level of the first buffered output voltage below a second voltage level of the second buffered output voltage in response to an open circuit condition.
