Prime Big Deal Days is underway, and we’ve already spotted some of the best generators we’ve tested on sale at Amazon. The best value generator, the Generac GP9500E Tri-Fuel Portable Generator, which ...

Have you ever wondered what made car manufacturers decide to go from dynamos to alternators for generating electricity? It's a mix of reliability and cost.

The harnessing of electricity has played a pivotal role in human history and has exponentially expedited our growth as a species. Since becoming a household commodity in the late 19th century, ...

In a dynamo, a split ring commutator changes the coil connections every half turn. As the induced potential difference is about to change direction, the connections are reversed. This means that the ...

Researchers have developed a new type of small-scale electric power generator able to produce alternating current through the cyclical stretching and releasing of zinc oxide wires encapsulated in a ...

This dual-fuel model is quiet and built to power sensitive devices and smart appliances. It’s also $1000, which makes it a great value.

Electricity comes in two basic forms: Alternating Current (AC) and Direct Current (DC). DC is handy to use and is easy to analyze. However, AC has some useful properties too. In particular, AC current ...

The LT3954, a DC/DC converter designed to operate as a constant-current source and constant-voltage regulator with an internal 5A switch, is now available from Linear Technology. The LT3954, a DC/DC ...

An electric current can be induced in in a coil of wire by moving a magnet in and out of the coil. AC generators are used in the generation of electricity and in their simplest form consist of a coil ...
