🔧 Como testar fuga em capacitores? Existem várias formas, mas as mais eficazes são com fonte de bancada ou multímetro analógico. Particularmente, prefiro a fonte, porque aplica uma tensão mais próxima da realidade. Já o analógico limita a cerca de 2 a 3V, o que nem sempre revela a fuga real. O teste com a fonte é simples e funciona até nas que não têm visor de corrente. 💧 Fuga em capacitor é como uma caixa d’água vazando: o dielétrico se deteriora e começa a deixar passar corrente.
