Question

mention the factors on which resistance of Conductor depends?write the corresponding equation​

Answer 1

● Length :

Length of the cunductor is directly proportional to the resistance offered by the cunductor.

i.e. R∝l

● Area of cross section :

Area of cross section of the cunductor is inversly proportional to the resistance of the cunductor.

i.e. R ∝ 1/A

●Nature of its material:

Resistance offered by cunductors vary as per the nature of the material of cunductor vary.

●Temperature.

When temperature increase , Resistance also increase

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; 1 = length; A= area
