In solar cells, solar radiation boosts electrons to higher energy states, thereby releasing them from their atomic bonds as electricity begins to flow. Scientists have now developed a novel method ...

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 ...

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.

To understand the difference between DC and AC, consider the flow of electrons in a wire. In a DC circuit, electrons move in one direction and keep rotating in the circuit.

To understand the difference between DC and AC, consider the flow of electrons in a wire. In a DC circuit, electrons move in one direction and keep rotating in the circuit.

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.

When a switch is thrown and current first flows in a DC circuit, a magnetic field builds up. The field can induce a current to flow in any nearby wire, but only briefly, just during the few ...
