The circuit was developed to produce a continuity tester with a low resistance mainly for checking the connections between soldered joints. Operational Amplifier (Op-Amp) – a DC coupled high gain ...

This is for all you die-hards who insist on testing DC electrical circuits on farm equipment with those darned, antique test lights. You know, the testers that look like a pointed screwdriver, with a ...
