Detailed Solution

Concept- The resistivity or specific resistance of a material is an intensive property and depends only on material and temperature. A circuit component or device's electric resistance is determined by the relationship between the voltage supplied and the electrical current that passes through it. Question ImageThe temperature and the material used to make the wire both affect its specific resistance. Due to the resistance that is provided per unit length and unit cross-sectional area when a voltage of known value is applied, specific resistance is also clearly defined.
A cloth's resistivity, also known as specific resistance, is an intense feature that only depends on the fabric and temperature.
The specific resistance of a wire depends only on the fabric of the wire and not on the size of the wire since specific resistance is an inherent feature of wire fabric.
Specific resistance is another name for resistivity.
The resistivity is a measure of the fabric's resistance. For example, the fabric has a cross section with a cross sectional area of 1 square meter and a length of 1 meter. The ohm meter is the SI unit for resistivity. The absence of charges moving through a conductor is known as resistance. As a result, resistivity is sufficient for the conductor's resistance with a unit cross-sectional area and unit length.
Hence, the answer is material,temperature.
