One of the core features of the scientific community is the concept of “peer review” where any claims made by a scientist are open to be analyzed and reproduced by others in the community for ...

Some kind of continuity beeper has been a standard piece of gear since the dawn of electronics. Sure, you probably have an ohm meter, but sometimes you don’t care about the actual resistance. You just ...

When working on electrical projects around the home—whether that’s troubleshooting an issue with your HVAC system, repairing an appliance, or testing a car battery—a multimeter is essential. These ...

I WAS REMINDED RECENTLY of a tester I designed years ago. At the time, I wanted to build “The Ultimate Continuity Tester,” and I established a wish list of all the features I required: • A “real ...

Wire Continuity Tester : While detecting discontinuities on a circuit board, it is probable to include resistors, semiconductors or other elements in measurements. This situation may cause wrong ...

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 ...

Back in the early days of electricity, lab workers could measure electric current in a circuit using an ammeter (galvanometer) and voltage using a voltmeter. From there, they could calculate ...
