Question

The resistance of a wire depends on:

A) Length and temperature
B) Color and thickness
C) Density and conductivity
D) Voltage and current

Answer 1

The resistance of a wire depends on its length and the material it is composed of.

Step-by-step explanation:

Resistance of a wire depends on its length and the material it is composed of.

The longer the wire, the higher its resistance because there will be more collisions between charges and atoms. Additionally, the resistance is inversely proportional to the cross-sectional area of the wire, meaning that a thicker wire will have lower resistance.

For example, a long and thin wire will have higher resistance compared to a short and thick wire made of the same material.
