Question

what is the resistivity of an alloy of Copper and Nickel​

Answer 1

Answer:

1)Alloy proportion->  90–10

 Resistivity ->  19 μOhm·mm

2)Alloy proportion->  70–30

 Resistivity ->  34 μOhm·mm

Answer 2

Answer:

• resistivity= resistivity is a inversely proportional of conductivity . it is fundamental property which show how strongly resists to flow of electron in a material .

• the resistivity is commonly represented by greek letter rho ρ

• resistivity is a different for different materials .

• SI UNIT of resistivity is a siemen per meter

• here are some examples of different materials and their resistivity

• copper =1.68 ×10 ⁻₈

• nickel= 6.99 ₓ10⁻₈

• zinc = 5.90  ×10 -8
