Por que o sinal de 4-20 milíamperes nos sinais dos instrumentos não é de 0-20 milíamperes?

Desde que a condutividade faça com que a corrente elétrica seja zero, fica difícil entender como isso acontece

Sinais muito fracos são instáveis; se for zero, como será possível haver condução de eletricidade?

Para separar o ponto zero do sinal do ponto zero elétrico.
