What is resistance of a wire ? What are the factors on which resistance of a conductor depends ?

Explanation

The resistance of a conductor depends on the following factors
(i) Length of the wire (1).
Resistance is directly proportional to the length of wire, i.e., `R prop l.`
(ii) Area of cross-section
Resistance is inversely proportional to the area of cross-section i.e., `R prop` 1/A.
(iii) Nature of wire i.e., material of which the wire is made of
(iv) It also depends on temperature.
