Question

What are the factors on which resitence of a conductor depends

Answer 1

Explanation:

The resistance of a conductor depends on the cross sectional area of the conductor, the length of the conductor, and its resistivity.

Answer 2

➠ AnSwer :-

➝ 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.

4) Resistivity:

• It is directly proportional to resistance of the conductor.

➝ Formula showing relation of resistance with these factors.

R = (p*l)/A

where,

• R = resistance
• p = Resistivity
• l = length
• A = area
