Abstract:	Schlumberger and Wenner vertical electrical soundings (VES) were carried out at five locations each within the campus of University of Agriculture, Abeokuta, Nigeria, with the aim of imaging the subsurface using different current values varying from 0.2 A to 20.0 A at each location as it appears on an ABEM SAS300B terrameter. The results of the interpretation for both electrode arrangements revealed six geo-electric layers: topsoil, sandy clay, clayey sand, sandstone, shale/clay and fresh basement. The work revealed that a current range of 0.2–1.0 A is ideal for both Schlumberger and Wenner arrays in a basement terrain.
