Detail

The electric potential energy of a charge is the product of the charge and the potential.

Intuitive explanation

La energía potencial eléctrica mide la energía asociada a la posición de una carga en un campo eléctrico.

Derivation

Para dos cargas puntuales,

U=k_e q_1q_2/r

proviene del trabajo para traerlas desde el infinito.

Worked example

Dos cargas de

1\,\mathrm{\mu C}

separadas

0{,}10\,\mathrm{m}

tienen

U\approx 0{,}090\,\mathrm{J}

.
