Question

Arrange the following metals in increasing resistivities chromium, nickel, manganese, iron.

• A. Nickel-Iron-Manganese-Chromium
• B. Nickel-Iron-Chromium-Manganese
• C. Manganese-Chromium-Iron-Nickel
• D. Chromium-Iron-Manganese-Nickel

Answer 1

The correct option is B Nickel-Iron-Chromium-Manganese

• Resistivity of Nickel is $6.85\times {10}^{-8}\Omega m$.
• Resistivity of Iron is $9.71\times {10}^{-8}\Omega m$.
• Resistivity of Chromium is $13\times {10}^{-8}\Omega m$.
• Resistivity of Manganese is $185\times {10}^{-8}\Omega m$.
• So, the order is $Nickel-Iron-Chromium-Manganese$.
