Para muitos esse é um assunto polêmico, pois alguns aprenderam de forma equivocada o funcionamento do capacitor. Para muitos, a corrente passa normalmente entre os terminais do capacitor. Mas isso é simplesmente impossível, pois o dielétrico é um material isolante e ele existe para que o capacitor consiga armazenar cargas. E se ele é isolante, as cargas não passam por ele. Claro que o que foi mostrado no vídeo é um capacitor ideal. #fontechaveada #eletricidade #capacitor #diodos

Um teste simples, mas essencial: como verificar um capacitor com o multímetro. ⚙️ Antes de medir, sempre descarregue o capacitor. No modo continuidade, se o multímetro bipar direto, é sinal de curto e o capacitor pode estar com problema. Na escala de resistência, o valor tende a subir e depois cair, indicando que o capacitor está carregando. Já na função capacitância, compare o valor medido com o que está escrito no corpo da peça — diferenças grandes indicam defeito. Já segue nosso perfil
