Abstract
The cost and availability of electrical components have been a major challenge to
Nigerian scientists and engineers. Thus, this study aimed at investigating geological
material (clay) to alleviate the challenge facing the field of science and engineering.
The study determined the electrical resistivity and conductivity of a geological
material from three different locations in Ilorin West Local Government Area,
Kwara State: Egbejila, Oko-Erin and Baboko. The samples were sieved, molded
into cylindrical form and dried. Thereafter, their electrical properties were
determined using electrical method. The resistance of the samples was determined
from the voltage-current (V-I) graph. Consequently, the resistivity was determined
by using sample’s resistance, area and length. The conductivity was calculated from
the reciprocal of resistivity. The electrical resistivity and conductivity of the
samples from Egbejila, Oko-Erin and Baboko were 0.0850 m and 11.7647 (m)-
1
, 0.0924 m and 10.822 (m)-1
, and 0.0251m and 39.841 (m)-1
respectively.
The result obtained from the study showed that the geological material (clay) can be
used as alternative material for industrial (based) resistor, the study further reduced
the stress, cost, and non-availability of resistors’ importation and thereby our locally
made geological material can be used as a substitute.
