The X-ray diffraction pattern manifest the orthorhombic structure for all the members of the series Gd1-xYxMn2O5. We calculate the particle size and unit cell volume from the diffraction data. We also calculate the x-ray, bulk density and porosity. The optical energy gap observed with the UV – Visible spectrophotometer for the end members of the series. The electrical properties such as electric current, DC resistivity ( ) and dielectric properties like real part of complex permittivity ( ), dielectric loss (tan?) and AC conductivity ( ) have been studied for  perovskite Gd1-xYxMn2O5 with substitutions (x=0,0.2,0.4,0.6,0.8,1). The activation energy for the perovskite samples Gd1-xYxMn2O5witht substitutions (x=0,0.2,0.4,0.6,0.8,1) calculated form DC and AC measurements. Both results are in good agreement with each other and in consistent with the estimated optical band gap for the material
