As the primary switching device used in a broad range of power conversion applications, MOSFETs play a central role in power supply design. Defining their performance characteristics is crucial to ...

You need to know how to measure the current that flows through a component in a circuit and the voltage across it. The ammeter must be connected in series with the component – remember, in a series ...

The National Electrical Manufacturers Association (NEMA) has published SG 4-2009 Alternating Current High-Voltage Circuit Breakers. The standard, which NEMA published under license from IEEE, was ...

You often need to measure current during circuit design and debugging. You can perform that task by breaking a path, inserting a shunt resistor, measuring its voltage, and converting the voltage to ...

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 ...

The new Fluke 377 FC and 378 FC Non-Contact Voltage True-rms AC/DC Clamp Meters can measure voltage and current simultaneously without touching a live wire EVERETT, Wash.--(BUSINESS WIRE)--Any time an ...

Current is a measure of how much electric charge flows through a circuit. The more charge that flows, the bigger the current. Current is measured in amperes. The symbol for ampere is A. For example, ...

Key differences in analog vs. digital features. Applications where each type of multimeter is best suited. Multimeters, from small handheld to more sophisticated benchtop models, are indispensable ...

Monitoring the current taken by a mains-powered appliance can be a challenge, particularly if the application demands an inexpensive solution that must provide galvanic isolation for user safety.

If you have ever read advanced textbooks or papers about electronics, you may have been surprised to see the use of complex numbers used in the analysis of AC circuits. A complex number has two parts: ...
