Question

On what factors does the resistance of a connecting wire depends ?

Answer 1

Explanation:

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

• The resistance of a conductor depends upon the resistivity, length and cross-sectional area of the conductor which is given by the relation:-

R = 1

ρ ---

• It does also depend on other physical factors like temperature etc. Its SI unit is Ohm (Ω).
