Question

define resistivity class 10​

Answer 1

Answer:

Hyyy

Explanation:

Resistivity is defined as the electrical resistance of a conductor of unit cross-sectional area and unit length. The resistance of any conductor is directly proportional to the length of the conductor and inversely proportional to the area of cross-section of the conductor. SI unit of resistivity is ohm-meters.

Answer 2

Answer:

hope it will help u.....

Explanation:

Resistivity, electrical resistance of a conductor of unit cross-sectional area and unit length. ... A characteristic property of each material, resistivity is useful in comparing various materials on the basis of their ability to conduct electric currents. High resistivity designates poor conductors.
