What happens to resistance of the conductor when area of cross section increases

What happens to resistance of a conductor if area of cross section is doubled?

What happens to the resistance of a conductor when its aru of cross-section is increased ?

What happens to resistance of the conductor when length is doubled

What happens to the resistance of a conductor when temperature is increased?

What is the effect on resistance, if the area of cross section is increased.

Resistivity of the material of a conductor of uniform area of cross-section varies along its length as p=p_0(1+alphax) Find the resistance of the conductor if its length is L and area of cross section is A.
