DAll the above

The resistance of a metallic conductor depends on its length, its area of cross section, and the temperature.

1. Length: The longer the conductor, the more resistance it will have. This is because electrons moving through the conductor will have a greater distance to travel and will therefore encounter more collisions with the atoms in the material.

2. Area of cross section: The larger the cross-sectional area of the conductor, the less resistance it will have. This is because a larger area allows more paths for the electrons to travel through, reducing the likelihood of collisions.

3. Temperature: As the temperature of the conductor increases, so does its resistance. This is because the atoms in the conductor vibrate more at higher temperatures, which increases the likelihood of collisions with the electrons.

Therefore, all of the above factors - length, area of cross section, and temperature - affect the resistance of a metallic conductor.
