Branch circuit wiring problems lead to more residential electrical fires than any other single cause. Hidden trouble inside a branch circuit can also lead to electrocutions and the failure of ...

You can avoid solving simultaneous equations in multiple unknowns by identifying series and parallel combinations of resistors.

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 ...

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 ...

Adaptive testing in integrated circuits (ICs) has emerged as an innovative strategy to optimise and streamline the evaluation of increasingly complex semiconductor devices. By incorporating machine ...

Wherever circuits need protection against current overloads or short circuits, you’ll find circuit breakers. They range from fingernail-sized devices for semiconductor protection to truck-sized ...

There are a number of complex tasks involved in the manufacturing of electronic assemblies, all of which can go wrong. In order to ensure quality standards are met, the fabrication of the printed ...

The Joint Test Action Group (JTAG) was formed in mid 1980s to develop a method of verifying designs and testing printed circuit boards after manufacture. Prior to the development of JTAG, testing and ...

At-speed testing and delay defect analysis have become increasingly critical in ensuring the reliability and performance of modern integrated circuits. As circuit complexity grows alongside rapid ...

Testing for failure with a multimeter is only partially effective, whereas a dedicated optocoupler testing circuit provides ...
