**1**. The resistivity of homogeneous, isotropic ground that would give the same voltage-current relationship as measured. **Direct current apparent resistivity**, ρ_{a}, is an Ohm’s-law ratio of measured voltage *V* to applied current *l*, multipled by a geometric constant *k* which depends on the electrode array: ρ_{a}=*kV*/*l*. Usually has units of ohm-meters. See *resistivity*.
