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 ...

If you’re like me, you have hazy memories from high school physics class about the difference between alternating current (AC ...

The world of electric vehicles can sometimes seem like it comes with its own vocabulary, and that's where we come in. Look out for our ABC of EVs series, to demystify the words and phrases you'll hear ...

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 ...

There are two main types of electrical current that flow through your home: Alternating and direct. The vast majority of devices around you are powered by alternating current. By allowing electrons to ...

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 ...

High-temperature superconductors (HTS) offer a way to deliver bulk DC power at low voltages, without the copper bloat or ...

Measuring AC current (220-V mains RMS current) is not as simple as measuring DC current. In DC current measurement, you can simply hook the oscilloscope probe to the shunt resistor and calculate the ...

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 ...

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 ...

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.
