Question

Quizplus · Accepted Answer

R2 can be proportionally higher than R1 and Rn if it has a smaller cross-sectional area. This is because resistance is inversely proportional to the cross-sectional area of the conductor, according to the formula R = ρL/A, where R is resistance, ρ is the resistivity of the material, L is the length of the conductor, and A is its cross-sectional area.
