Two metallic conductors have the same value of resistivity. These conductors can be differentiated from the values of their
Correct answer: B. Resistance
- A. Temperature coefficient
- B. Resistance
- C. Conductance
- D. Conductivity
Explanation
Even if two metallic conductors have the same resistivity, their resistances may differ depending on their dimensions (length, cross-sectional area). Measuring their resistance values can differentiate between them.

About Current Electricity
Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
