O QUE SIGNIFICA CATHODE EM INGLÊS
Cátodo
Um cátodo é o eletrodo a partir do qual uma corrente convencional deixa um dispositivo elétrico polarizado. Essa definição às vezes é lembrada usando o CCD mnemônico para corrente de cátodo parta. Uma corrente convencional descreve a direção que a carga eletrônica positiva se move. s têm uma carga negativa, então o movimento de elétrons é oposta ao fluxo de corrente convencional. Consequentemente, a corrente de cátodo mnemônica parte também significa que os elétrons fluem para o cátodo do dispositivo. A polaridade do cátodo em relação ao ânodo pode ser positiva ou negativa; Depende de como o dispositivo opera. Embora os catiões carregados positivamente sempre se movam em direção ao cátodo e os aniões carregados negativamente se afastem, a polaridade do cátodo depende do tipo de dispositivo e pode variar de acordo com o modo de operação. Em um dispositivo que consome energia, o cátodo é negativo, e em um dispositivo que fornece energia, o cátodo é positivo: ▪ Em uma bateria de descarga ou uma célula galvânica, o cátodo é o terminal positivo, já que é onde a corrente flui para fora o dispositivo.
definição de cathode no dicionário inglês
A primeira definição de cátodo no dicionário é o eletrodo negativo em uma célula eletrolítica; o eletrodo pelo qual os elétrons entram em um dispositivo a partir de um circuito externo. Outra definição de cátodo é a fonte de elétrons carregada negativamente em uma válvula eletrônica. O cátodo também é o terminal positivo de uma célula primária.
