AB  - Results of measurement of ground electrical measurement are usually important to many branches of engineering communication, geophysics, hydrological, mineral explorations and earthling of transformer in the electrical power networks. To achieve this, a better and simpler method-core sampling was employed in this study with objective of detecting smaller intensity of voltage or current that passes through the soil. The measurement was carried out using a direct current on three different types of soil namely, Clay, Loam and Sand soil and this took three different forms of wet, moist and dry. The mean ground electrical conductivity obtained in  this  study  area  are  from  1.04&plusmn;0.002  mS m <SUP>1</SUP>  for  loam  soil,  0.99&plusmn;0.002  mS m <SUP>1</SUP>  for  clay  soil  and  0.39&plusmn;0.001 mS m <SUP>1</SUP> for sand soil, while for the wet soil 1.23&plusmn;0.002 mS m <SUP>1</SUP> for loam soil, 0.43&plusmn;0.001 mS m <SUP>1</SUP> for sand soil and 0.52&plusmn;0.001 mS m <SUP>1</SUP> for clay soil. The results were found to be in agreement with the results of previous researchers.
