Variable capacitors may be useful, but the air gap that provides their capacitance is their greatest weakness. Rather than deal with the poor dielectric properties of air, some high-end variable ...

Enterprises can now harness the power of a large language model that's near that of the state-of-the-art Google’s Gemini 3 Pro, but at a fraction of the cost and with increased speed, thanks to the ...

Researchers from the University of Arkansas in the United States have fabricated a graphene-based solar cell that can be used in Internet of Things (IoT) applications. The device was developed in the ...

A capacitor, along with resistors and inductors, belongs to a group of components known as passive devices. These components do not produce or amplify energy; instead, they can only store, absorb, or ...

The surprising inroads that Donald Trump made in traditionally Democratic nonwhite areas of New Jersey in 2024 have added an unpredictable variable into this year’s governor’s race. For Republican ...

Radio experimenters often need a variable capacitor to tune their circuits, as the saying goes, for maximum smoke. In decades past these were readily available from almost any scrap radio, but the ...

The science pros at The King of Random build a low-cost variable power controller and explain how it works. Donald Trump to make televised announcement from Oval Office: What to know Cracker Barrel ...
