a. Resistance, R, of a block of specified material in terms of units of
length 1 and cross section a. Unit volume is 1 cm3 of the
material concerned, and the resistivity measurement is made during
electrical prospecting. Specific resistance = (Ra) / 1. Pryor, 3
b. The electrical resistance offered to the passage of a current. Usually
expressed in ohm meters, which is the electrical resistance of a column of
fluid 1 m long and 1 m2 in cross section. Brantly, 1
c. The opposite of conductivity of an electrical current passing through
fluid-bearing rock formations. Wheeler, R.R.
d. The electrical resistance between opposite faces of a 1-cm cube of a
given substance. The unit of resistivity is ohm/centimeter. Hy
e. The reciprocal of conductivity. Syn: thermal resistivity Strock, 2
