Question

write down value of resistivity of al and CU​

Answer 1

Answer:

Material Resistivity ρ (ohm m)

Silver 1.59 x10-8

Copper 1.68 x10-8

Copper, annealed 1.72 x10-8

Aluminum 2.65 x10-8

Answer 2

Value of resistivity of al and CU​:

• The value of resistivity for aluminium (Al) ranges from 2.65 to $2.82 \times 10^8$ Ω m.

• The value of resistivity for copper (Cu) is $1.68 \times 10^8$ Ω m.

Resistivity is basically the measure of how much resistance a material causes in terms of conductivity of electricity.

Resistance (in physics) is the opposing force of any conductor when electricity is passes through it.

Resistance of any material is what determines its conductivity. Resistance and conductivity share an inverse relationship with each other.
