Which factor does not influence the resistance of a conductor?

• A. The material of the conductor
• B. The length of the conductor
• C. The shape of the conductor, if material and length are constant
• D. The temperature of the conductor

Answer: (C)

The resistance of a conductor is influenced by several factors, but when the material and length are held constant, the shape of the conductor does not affect its resistance. This is because resistance is defined as the ratio of voltage to current, and it depends on specific properties of the material and its dimensions. While the geometric shape can influence how the conductor is used in a circuit (such as whether it is braided, hollow, or solid), the fundamental property of resistance for a given material of a specific length and cross-sectional area remains constant. Resistance is more directly related to the inherent resistivity of the material, the total length of the conductor, and the temperature. Therefore, when considering how resistance varies under constant conditions of material and length, the shape does not play a role.
