Every year we read about electricians, engineers, and supervisors who were seriously burned or killed while working in or near a circuit breaker (CB) compartment. I’ve personally investigated ...

Production test of a finished electronic product often involves two techniques: in-circuit test (ICT) and functional component test (FCT). The ICT technique examines a non-powered circuit board to ...

Change in life is inevitable. You know this, yet sometimes you just choose not to accept it. You just close your eyes and think the world has also stopped. But even you realize that’s not the case. It ...

We have all had difficulty testing diodes in-circuit. Most DMM’s have a diode Vf function that measures forward drop, but what is the normal voltage drop? Analog VOM’s attempt to measure resistance of ...

Electrical and electronic circuits are around us. From our mobile phones to security systems, electronic circuits are everywhere. Designing a circuit follows a step-by-step procedure. Most of the time ...

All engineers know resistance is usually bad news. It generates heat. It reduces efficiency. It wears out components and cuts operational lifetimes. However, resistance is not the only kind of ...
