Representa a taxa na qual a carga el\u00e9trica passa por um ponto em um circuito. Geralmente, esse fluxo \u00e9 conduzido por el\u00e9trons, que s\u00e3o part\u00edculas com carga negativa. A unidade SI para corrente \u00e9 o coulomb por segundo, ou ampere (A), que \u00e9 uma unidade base do SI: 1 ampere = 1A = 1 coulomb por segundo = 1 C\/s.<\/p>\n<h2>Corrente I\u00f4nica<\/h2>\n<p>Em materiais condutores de corrente, as cargas das part\u00edculas em movimento podem ser positivas ou negativas. Em metais, as cargas m\u00f3veis s\u00e3o sempre el\u00e9trons (negativos), enquanto em um g\u00e1s ionizado (plasma) ou solu\u00e7\u00e3o i\u00f4nica, as cargas m\u00f3veis podem incluir tanto el\u00e9trons quanto \u00edons positivos.

Ela \u00e9 um componente prim\u00e1rio na inicia\u00e7\u00e3o de rea\u00e7\u00f5es de corros\u00e3o em metais. A unidade de medida da corrente i\u00f4nica \u00e9 o ampere. A corrente i\u00f4nica pode ser encontrada em uma ampla gama de sistemas naturais e artificiais, como baterias, c\u00e9lulas de combust\u00edvel e sistemas biol\u00f3gicos.<\/p>\n<h2>Exemplos de Corrente I\u00f4nica<\/h2>\n<ul>\n<li><strong>Eletrolise:<\/strong> Eletrolise \u00e9 um processo que envolve o uso de corrente el\u00e9trica para conduzir uma rea\u00e7\u00e3o qu\u00edmica n\u00e3o espont\u00e2nea. Na eletrolise, uma corrente i\u00f4nica \u00e9 passada atrav\u00e9s de uma solu\u00e7\u00e3o ou material fundido, fazendo com que \u00edons se movam para os eletrodos e sofram uma rea\u00e7\u00e3o qu\u00edmica.<\/li>\n<li><strong>Baterias:<\/strong> As baterias s\u00e3o dispositivos que convertem energia qu\u00edmica em energia el\u00e9trica, criando uma corrente i\u00f4nica.
