InterviewSolution

1.	Use the data in Table 12.2 to answer the following Table 12.2 Electrical - resistivity of some substance at 20^(@)C
Answer» Solution : (a) RESITIVITY of iron `=10.0xx10^(-8)Omega` Resistivity of mercury`=9.4xx10^(-8)Omega` (a) Resistivity of mercury is more than that of iron.This implies that iron is a better conductor than mercury. (b) It can be observed from Table 12.2 that the resistivity of SILVER is the lowest AMONG the LISTED materials. Hence, it is the best conductor
