Question

How does resistance of a wire is influenced by its length and area of cross section?​

Answer 1

Answer:

It is inversely proportional to the area of cross section of the wire. The more the area of cross section of the wire,the less is the resistance and the less the area,the more is the resistance.

Answer 2

Answer:

The resistance of a wire is directly proportional to its length and and inversely proportional to its cross sectional area. Resistance also depends on the material of conductor . The resistance of the conductor or the circuit element generally increases with increasing the temperature .
