Every student in physics and electronic engineering learns Ohm’s law, E = I x R, or voltage equals current times resistance. You learn that E is electromotive force, a long term for voltage. R is ...

A new technique for embedding atomic-scale wires within crystals of silicon has revealed that Ohm’s law can hold true for wires just four atoms thick and one atom tall. The result comes as a surprise ...

Georg Ohm was a 28-year–old high school physics teacher in 1825 when he first decided to study the effect of the metal in a circuit on the current produced. This experiment was possible because five ...
