When choosing a switch to use in an electrical design project, there is a perception that it is possible to use any switch, provided its current rating is greater than the maximum load in the circuit.

Fuses protect against overcurrent events by melting their elements and opening the circuit. Fuses must be applied at or below their specified voltage rating, which differs between ac and dc current.

The battery as we know it today was an invention of Italian chemist and physicist Alessandro Volta. He witnessed electricity splitting water into its constituent elements of oxygen and hydrogen and ...

AC/DC power supplies are used in several electronic devices, encompassing computers, smartphones, radios, and TVs. AC/DC power supplies come in many dimensions and configurations, tailored to suit the ...

The demand for smaller, lighter, and more efficient AC/DC USB power delivery (PD) chargers is always a challenge for power-supply design engineers. Below 100 W, the quasi-resonant flyback is still the ...

Researchers at the US Department of Energy’s Oak Ridge National Laboratory (ORNL) are breaking technical barriers with faster circuit breakers to enable and protect the modern electric grid. The ORNL ...
