⚡ Você sabe qual é a função do varistor em uma placa eletrônica? ⚡ Você sabe qual é a função do varistor em uma placa eletrônica? O varistor é um componente de proteção que fica na entrada da alimentação da placa, monitorando a tensão da rede. Em condições normais ele apresenta alta resistência, praticamente como um circuito aberto. Mas quando ocorre um surto de tensão, ele reduz sua resistência e começa a desviar parte da energia, protegendo o circuito. #eletronica #eletrotecnica
