Question

What are the factors affecting the resistance of a conductor?

Answer 1

The factors affecting the resistance of a conductor are following-

1. The nature of the material
2. The temperature of the material
3. Length of the wire- The resistance $R$ is directly proportional to the length $l$ of the wire $R\alpha l$
4. Area of cross-section- The resistance $R$ is inversely proportional to the area of cross-section $A$ of the wire.

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