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 ...

As the story goes, the rock band AC/DC took its name from a label on an old sewing machine in the Young brothers’ home. It must have meant that the machine could run on either alternating-current or ...

Electric vehicles are an important wave of the future, offering motorists a cleaner and more efficient way to travel. But when it comes to charging their batteries, electric vehicles have a particular ...

DC current injection in grid-connected inverter systems represents a critical challenge in the integration of renewable energy sources. Inverters that interface photovoltaic panels and other renewable ...

Scientists at Scripps Research have used rapid alternating current (AC) to selectively reduce carbonyl groups (J. Am. Chem. Soc. 2021, DOI: 10.1021/jacs.1c06572). The technique avoids side reactions ...

Fluxgate current sensors have emerged as a robust technology for the measurement of both alternating and direct currents, harnessing the non-linear magnetic characteristics of ferromagnetic materials.

Let's start with DC voltage, one of the simplest and most-used multimeter measurements. The DC voltage measurement is used to determine the difference in electrical potential between two points in a ...
