This is the second part of a two-part series on the methodologies used to find the short circuit current duties of circuit breakers and fuses. The first part, Short Circuit Current Duties of Circuit ...

Current conveyor (CC) circuits are among the most common current-mode circuits and are used as critical building blocks in a variety of complex circuits. Unlike voltage-mode circuits, current-mode ...

Troubleshooting refrigeration equipment often requires measuring various electrical properties such as voltages, current flows, and resistances. Understanding these basic electrical fundamentals and ...

NEMA, Rossyln, Va., has published SG 4-2009, "Alternating Current High-Voltage Circuit Breakers." The standard, which NEMA published under license from IEEE, Piscataway, N.J., was revised by the ...

FET constant current sources use JFETs and MOSFETs to deliver a load current, which remains constant despite changes in load resistance or supply voltage. A FET constant current source is a type of ...

Part 1 of this series focuses on high-performance electronic loads for testing power supplies that have low output voltage and high current. It describes the necessity for special electronic loads, ...

Communications channels used to be a challenging exercise in pure analog design. Today, modulation occurs in the digital domain in many systems. But the transmitted signal is analog, so there’s always ...
