What is resistance?
Resistance is the opposition that a substance offers to the flow of electric current.
Factors on which resistance depends
1. Material of the conductor
2. Length of the conductor
3. Thickness of the conductor
4. Temperature
If R is resistance of a conducting wire of length L and thickness A then
R = ρL/A
Where ρ is specific resistance (constant) of wire which depends only on material of the wire.

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
