Question

define resistance and resistivity and also give the relation between them. explain the dependence of resistance on temperature​

Answer 1

Answer:

Relation between Resistivity and Resistance is: R=ρlA, where ρ is the resistivity, l is the length of the conductor and A is the cross sectional area. ... Thus, from the above relation we can say that the resistance of a material also increases or decreases with the increase and decrease in temperature
