Resistance of a conductor depends upon _.
Correct answer: C. Length
- A. Temperature
- B. Nature of conductor
- C. Length
- D. None of these
Explanation
Correct Option:CThe resistance of a conductor depends on various factors, but one of the primary factors is the length of the conductor. The resistance is directly proportional to the length of the conductor. This relationship is described by the formula:Resistance = (ρ * Length) / AreaWhere ρ (rho) is the resistivity of the material, Length is the length of the conductor, and Area is the cross-sectional area of the conductor.

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.
