Resistance in a material can depend on which of these factors?

Resistance in a material is influenced by several key factors, which include the type of material, its length, its diameter, and the temperature of the material.

Material type is crucial because different materials have different inherent properties that define how easily electricity can flow through them. For instance, copper has lower resistance compared to iron. The length of the conductor plays a significant role; as the length increases, the resistance also increases. This is due to the fact that electrons have to travel a longer distance, encountering more collisions with atoms in the material.

The diameter, or cross-sectional area, directly affects resistance; larger diameters provide more space for electrons to flow, thereby reducing resistance. On the other hand, as the temperature of a material increases, the atoms in the lattice vibrate more vigorously, which can impede electron flow and increase resistance.

Thus, the interplay of all these factors—material type, length, diameter, and temperature—determines the overall resistance of a conductor, making option C the most comprehensive and correct choice.
