When measuring electrical current, the goal is to insert an ammeter in series with the circuit so that the current measured by the ammeter is identical to the current flowing through the circuit. In ...

Current probes are one of my most-used EMI troubleshooting tools. Frequently, a product’s I/O or power cables are often an appreciable fraction of a wavelength, so are a source of radiated emissions.

Understanding the role of short-circuit current is critical to the reliability of your electrical system and to the safety of the people who maintain it. When designing or modifying a distribution ...

Physicists have made the first definitive measurements of "persistent current," a small but perpetual electric current that flows naturally through tiny rings of metal wire even without an external ...
