If you want an electrical current to flow around a normal metal ring you have to supply enough energy to overcome the metal’s resistance – right? Not always, according to physicists in the US and ...

A study showing how electrons flow around sharp bends, such as those found in integrated circuits, has the potential to improve how these circuits, commonly used in electronic and optoelectronic ...

How can data be processed at lightning speed, or electricity conducted without loss? To achieve this, scientists and industry ...

Therefore, a circuit that has 12A flowing through it will have three times as many electrons flowing through it as a circuit that has a current of 4A. Impedance is the total opposition to the flow of ...

Princeton Professor Ali Yazdani has led a team that has found electrons acting in unusual ways on the surfaces of specific materials. The work represents the first time such behavior of electrons has ...

A river erodes its course. In an electric circuit, does the wiring get eroded by the current, atoms, electrons etc? — Bill "It's a reasonable analogy to think of an electric current acting like ...

Potential difference in parallel circuits Since energy has to be conserved, the energy transferred around the circuit by the electrons is the same whichever path the electrons follow.

Different models, such as water flowing in a central heating system, can be used to understand electrical circuits. Find out more with BBC Bitesize. For students between the ages of 11 and 14.

The phenomenon represents a milestone in the emerging field of ‘atomtronics’, which seeks to create a whole new class of devices that use the flow of atoms, rather than electrons, in a circuit.

When atom clouds go with the flow Time to retire the old soldering iron? In the "atomtronic" circuits pictured on the right, it is atoms, not electrons, that flow. Such circuits could form the ...

Unusual electrons go with the flow Date: July 19, 2010 Source: Princeton University Summary: On a quest to discover new states of matter, a team of scientists has found that electrons on the ...
