For electricity to flow, everything needs to be connected in a big ring. It’s called a circuit. For example, the lights in most houses and flats are part of a circuit controlled by the consumer unit, ...

We all carry supercomputers in our pockets and use dozens of electric gizmos every day but rarely stop to marvel at the magical act of flicking a switch. Use your ordinary conducting and extraordinary ...

Resistors are small but essential components that manage how electricity moves through a circuit. This video explains how ...

Shini explores electric current, voltaic cells, and how we get electric charge. Electric current works like a river... kinda... Instead of flowing based on elevation ...

Short-circuit currents represent a tremendous amount of destructive energy, which can be released through electrical systems under fault conditions. Baseline short-circuit studies should be performed ...

Printed circuit boards (PCBs) are the essential building blocks behind almost all modern electronic devices. These components ...

Introduction Electricity powers many of the devices you use every day. Those devices are made up of circuits, ranging from very simple (such as a lamp with a single lightbulb) to very complex (such as ...

Mechanical relays, contactors, and switches control the flow of electricity by the mechanical action of two conducting elements. The physical contact of two conducting elements creates a path for ...

A NASA-funded rocket mission is headed to space to measure the global electric circuit underlying the northern lights. For its second trip to space, the Aurora Current and Electrodynamics Structures ...
