Question

what are the factors on which the resistance of a conductor depends​

Answer 1

Hey buddy here is your answer

The resistance of the conductor depends on the following factors

• Length of the conductor- The resistance of a conductor is directly proportional to the length of the conductor.
• Area of the cross-section of the conductor- The resistance of a conductor is inversely proportional to the area of the cross- section of the conductor.
• Temperature- The resistance of a conductor is directly proportional to the temperature around it.
• Nature is the conductor- The resistance of a conductor depends upon the nature of yhe conductor i.e the material used and its properties etc.

Hope it helps

Answer 2

What is resistance ?

Resistance is defined as the opposition to the flow of electrical current through a conductor.

It is the tendency of a material to oppose the flow of electrons through it.

What is resistivity ?

The property of an element which is used to determine its resistance capability is called Resistivity.

The resistivity of a conductor is always fixed for that element. For e.g. Copper and zinc has their own and unique resistivity.

* Resistivity is constant for an element whereas Resistance is variable.

FACTORS AFFECTING THE RESISTANCE OF AN ELEMENT :-

1. Length of an conductor.

Length is directly propertional to the resistance of the conductor.

.

$l \propto r$

2. Area of cross-section of conductor.

Cross section/Thickness is inversly propertional to the resistance of the conductor .

$r \propto \frac{1}{a}$

3. Temperature of the conductor.

Whenever the temperature of a conductor increases the electrons began to flow faster leading to increase in resistance.

4. Conductivity of the material

Resistance depends on capability of the material to carry electrons.
