ResumoBi2S3 single crystals were grown by a modified of Bridgman method. Measurements of the electrical conductivity, Hall effect and thermoelectric power (TEP) were preformed in two crystallographic directions (parallel and perpendicular to the c-axis). The measurements showed that the electrical conductivity, Hall mobility, and Seebeck coefficient have anisotropic nature. From these measurements many physical parameters were estimated and the crystals showed n-type of conduction mechanism. Also, values of the energy gap were found to be different in the two directions
