What is meant by electrical resistivity of a material? Derive its SI unit. Describe an experiment to study the factor on which the resistance of a conducting wire depends

Answered by admin @ 11/08/2021

Answer:

Electrical resistivity (also called specific electrical resistance or volume resistivity) and its inverse, electrical conductivity, is a fundamental property of a material that quantifies how strongly it resists or conducts electric current. The SI unit of electrical resistivity is the ohm-meter (Ω⋅m).
