Eletrônica Aplicada
Quando você liga um equipamento eletrônico, os capacitores da fonte estão completamente descarregados. E capacitor descarregado, em corrente contínua, se comporta quase como um curto-circuito no instante inicial. Isso faz com que, no momento em que a placa é energizada, circule uma corrente muito alta por alguns milissegundos. Essa corrente é conhecida como corrente de inrush. Apesar de durar pouco tempo, ela pode causar estresse elétrico aos componentes.
