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 ...

When working around mains voltages, it can be useful to know whether a given circuit is live or not. While this can be done by direct connection with a multimeter, non-contact methods are available ...

Left panel, superconducting rectifier circuit used to convert AC currents into DC using four superconducting diodes (blue) connected by superconducting interconnects and one smoothing capacitor (C) ...

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 ...

Inrush current/Switch-ON surge is the maximal instantaneous input current drawn by an electrical device when first turned on. Inrush current is much higher than the load’s steady-state current and ...

The easy way to measure high AC currents is to use a clamp meter but these are generally quite expensive and cost several hundred dollars at a minimum. Add-on clampmeter adaptors can work well but ...

Pulse Electronics Corporation introduces its new Sidewinder™ AC current sensors. Sidewinder products differ from traditional current sense transformers because they do not need a core. This makes them ...
