Giant electrical circuits power the magical open-air light show of the auroras, forming arcs in high-latitude regions like Scandinavia. New results obtained thanks to ESA's Cluster satellites provide ...

For the first time, researchers demonstrate a new type of magnetocapacitance, a phenomenon that could be useful in the next generation of 'spintronic' devices. Capacitors, electronic components that ...

Switch is an electronic device which stops the circuit and transmits the current to conducts. It is a binary devices which means that it has two states; the on state or “closed”condition or off state ...
