Resistance is the property of opposing the electric current through anything. There are several factors on which resistance depends which are follwing :-
Resistivity :- Resistance depends upon resistivity which is a proportionality constant and depends on nature of substance and temperature.
Temperature :- As the temperature increases, the value of resistivity increases so resistance increases . (In the case of conductors or simply metals).
Length :- Resistance is directly proportional to the length . So as the length increases the value of resistance increases.
Cross Section Area :- Resistance is inversely proportional to the cross section area . So as cross section area increases the value of resistance decreases.
Hope it helps :-)

Resistance depends on following factors: 1) Length: It is directly proportional to resistance of the conductor. 2) Area: It is inversely proportional to resistance to the cross sectional area of the conductor. 3) Temperature: It is directly proportional to resistance
