A fórmula para calcular a resistência de um condutor de acordo com a segunda lei de Ohm é R = (ρ * L) / A, onde R é a resistência, ρ é a resistividade do material do condutor, L é o comprimento do condutor e A é a área transversal do condutor. A alternativa correta é a letra "c) Ambas as afirmações estão corretas".
