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 ...

Why are test points a crucial element in developing a successful circuit? Types of test points available, and the different techniques that employ them. Electronic design has always been an endeavor ...

The importance of properly integrating test points into a PCB design. Test-point deployment considerations. When it comes to creating a modern electronic design, we live in both the best and the worst ...

Modern printed circuit board assemblies (PCBAs) are designed to support increasingly complex applications in industries such as telecommunications, automotive, consumer electronics, and industrial ...

A blast from the Elektor archives: this 1998 battery tester uses a simple LED display to reveal a battery’s true condition under load — even below 1 V.

Designing, constructing, testing, and improving circuits—especially those with significant analog content—was always one of my interests. The fact that you could arrange standard active and passive ...

A circuit is a closed loop containing various components. Electrical current flows around the circuit. Scientists use symbols to represent the different components in a circuit. Symbols are simplified ...

For electricity to flow, everything needs to be connected in a big ring. It’s called a circuit. For example, the lights in most houses and flats are part of a circuit controlled by the consumer unit, ...
