Which of the following is the correct order of conductivity (in \( \text{S m}^{-1} \))?
Show Hint
Silver has highest electrical conductivity.
Updated On: Apr 21, 2026
- \( Fe<Na<Cu<Ag \)
- \( Fe<Cu<Na<Ag \)
- \( Ag<Na<Cu<Fe \)
- \( Ag<Cu<Na<Fe \)
- \( Na<Fe<Cu<Ag \)
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
Conductivity depends on free electrons.
Step 1: Order.
\[ Ag>Cu>Na>Fe \] Thus increasing order: \[ Fe<Na<Cu<Ag \]
Step 1: Order.
\[ Ag>Cu>Na>Fe \] Thus increasing order: \[ Fe<Na<Cu<Ag \]
