. How does the resistance of a conductor depend on


How does the resistance of a conductor depend on: (a) length of the conductor? (b) area of cross - section of the conductor ? (c) temperature of the conductor?

Best Answer

Explanation

The resistance of the conductor is 

  • directly proportional to the length of the conductor and
  •  inversely proportional to the cross - section area of the conductor. 
  • It is mathematically expressed as
  •  temperature

The temperature dependency of the conductor is given as

temperature

Final answer

Hence, the resistance of the conductor is directly proportional to the length of the conductor and inversely proportional to the cross-section area of the conductor. The dependency on temperature for the resistance of the conductor is linear.
