Electrical properties of QCD plasma is an important tool to understand the behaviour of strongly interacting matter in different physical conditions. It will help us to understand the effect of electromagnetic interaction with strongly interacting QCD plasma. Recently, it has been shown that a strong magnetic field is created during heavy ion collisions. Thus it is interesting to study the effect of this magnetic field on the transport and thermodynamical properties of matter created in these heavy ion collisions. In this poster, we will show the variation of electrical conductivity of an isotropic quark gluon plasma with respect to temperature. Further we will demonstrate the effect of magnetic field on electrical conductivity and discuss its physical importance.
