The simplest complete circuit is a piece of wire from one end of a battery to the other. An electric current can flow in the wire from one end of the battery to the other, but nothing useful happens.

Fran: Ahhh, I almost won that one as well! Now, our appliances and devices, they all work because of the electrical current that flows into them through a circuit. An electrical circuit is made of a ...

A weird phenomenon in which electricity flows like water was spotted in a nanowire made of "strange metal" — a bizarre metal phase that has stumped physicists for 40 years. When you purchase through ...

Strange metals defy the 60-year-old understanding of electric current as a flow of discrete charges. (Nanowerk News) We all learned that electricity is caused by electrons moving in a metal. Each ...

In a strange metal (translucent box), electrons (blue marbles) lose their individuality and melt into a featureless, liquid-like stream. We all learned that electricity is caused by electrons moving ...

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 ...

Quantum metals are metals where quantum effects—behaviors that normally only matter at atomic scales—become powerful enough to control the metal's macroscopic electrical properties. Researchers in ...

Conductors are materials that allow electric current to flow with minimal resistance and are essential for transmitting power and electrical signals in electronic devices. Most metals are good ...
