An apparatus and method for automatic control of current electrodes in a measuring system for an electrical resistivity survey. An exemplary apparatus includes: a circuit where one pair of metal oxide semiconductor field effect transistors (MOSFETs) are connected to upper and lower terminals of n current electrodes and the one pair of MOSFETs are connected in parallel with each other; and a controller which controls ON/OFF of each MOSFET.With this, the present invention provides a stable and semipermanent apparatus for automatic control of current electrodes, which is capable of bipolar high-speed switching, and a method thereof.
