Para calcular a resistividade (ρ) da liga, podemos usar a fórmula: ρ = (R * A) / L Onde: R = resistência medida (em ohms) A = área da seção transversal do fio (em metros quadrados) L = comprimento do fio (em metros) Primeiro, precisamos calcular a área da seção transversal do fio, usando o diâmetro fornecido (2mm): A = π * (d/2)^2 A = π * (0,002m/2)^2 A = π * (0,001m)^2 A = 3,1416 * 0,000001m A =
