Ela \u00e9 usada para calcular a quantidade de pot\u00eancia el\u00e9trica que um dispositivo consome ou transfere. A pot\u00eancia el\u00e9trica \u00e9 o ritmo pelo qual a energia el\u00e9trica \u00e9 convertida em outra forma de energia, como calor, luz ou energia mec\u00e2nica.

Quando conhecemos a resist\u00eancia el\u00e9trica (R) de um dispositivo, podemos usar a lei de Ohm, juntamente com a f\u00f3rmula da pot\u00eancia el\u00e9trica.
