Cours Électricité

Electricity is the effect of the movement of charged particles inside a conductive material, under the effect of a potential difference at the ends of the latter. This physical phenomenon is present in many contexts: electricity constitutes both the nerve impulse of living beings and the lightning of a thunderstorm. The discoveries of the natural laws of electricity have led to the invention of many techniques grouped together in electrical engineering. The latter is widely used in developed societies, for example to transport large amounts of easily usable energy.
