Question

Match the properties in Column A with their respective unit in Column B:

• A. P-1; Q-3; R-4; S-2
• B. P-2; Q-3; R-1; S-4
• C. P-3; Q-1; R-2; S-4
• D. P-3; Q-1; R-2; S-4

Hint:

When dealing with properties like resistivity and conductivity, always check their standard units in terms of electrical properties: resistivity in Ohm-cm and conductivity in S cm\(^{-1}\).

Answer 1

The Correct Option is C

Let's match the properties with their respective units: - P. Surface resistivity has the unit of Ohm-cm. Hence, the match is \( P-1 \).
- Q. Volume resistivity is measured in Ohm-cm, hence it corresponds to unit 3 in Column B. So, \( Q-3 \).
- R. Coefficient of thermal expansion has units of K\(^{-1}\), so \( R-4 \).
- S. Electrical conductivity has the unit of S cm\(^{-1}\), so \( S-2 \).
Thus, the correct answer is option (A).
