Abstract
An apparatus for measuring induced polarization of the ground. The apparatus includes a polarizable contact member configured to transmit a current to the ground. An electrode includes a first conductor and a second conductor. The first conductor is coupled to the polarizable contact member. A non-polarizable contact member is coupled to the second conductor of the electrode and is configured to measure an electrical potential associated with the current.
