Ohm. Because of that surface resistivity and the surface resistance are often mixed up. In order to differentiate between the two, surface resistiv-ity is often expressed also in Ohm/square (Î©/sq.) which is not a valid unit from the dimensional anal-ysis point of view. 2 Surface resistivity and surface resistance 2.1 Current density and surface cur-
The median age of the world's population was estimated to be 30.1 years in 2016, with the male median age estimated to be 29.4 years and female, 30.9 years.
The literacy rate of females, which was 8.86% in. 1951 rose to 54.16% in 2001. Womenâs work participation rate, which was 19.7% in 1981, rose to 25.7% in 2001. The data base also brings out the areas where the progress has. been slow if not retrograde. The sex ratio in the 0-6 years age group dropped from 945 in.
