Question

On what factors does the resistance of a conductor depends. Explain with the expression.

Answer 1

Answer:

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

examples

The resistance of the conductor depends on the following factors: The temperature of the conductor. The cross-sectional area of the conductor. Length of the conductor

Answer 2

Hi there!

Here's your answer:

Resistance depends on

• Length
• LengthCross- Section Area
• LengthCross- Section AreaResistivity of the material

This is how the formula for Resistance is derived:

Resistance is directly proportional to Length and inversely proportional to the Area of Cross- Section

$R \: \alpha \: l$

$R \: \alpha \: \frac{1}{A}$

$R \: \alpha \: \frac{l}{A}$

Adding the proportionality constant, Resistivity(written as p below), we get:

$R \: = \: p \times \frac{l}{A}$

Hope this helps.

Thanks.
