Qual é a fórmula para calcular a razão entre a corrente elétrica e a diferença de pressão?

(400-100) / (500-100) = (x-4) / (20-4). Assim, x = 16 mA

(Medida – Limite inferior da escala) / (Limite superior da escala – Limite inferior da escala) = (Valor da corrente – 4mA) / (20mA – 4mA)

Aprender para aplicar, tirar conclusões a partir de um exemplo, repetir o processo. Esses são os dois pontos ensinados pelos professores do ensino fundamental.:lol

...o limite inferior da escala corresponde a 4mA, e o limite superior a 20mA, assim você entende, certo?
