Graphene, due to its numerous unique properties, is addressed as miraculous material by Novoselov et al. [Nature 490 (2012) 192]. It has ultrahigh heat and thermal conductivity. Several researchers over the globe are working on electrical properties of graphene like electrical resistance, electrical conductivity etc. In this paper, we estimate electrical resistivity, electrical conductivity and Lorenz number for graphene within the temperature range from 300 K to 500 K. Variation of these parameters with respect to temperature and sample size is also reported.
