How to get current from current source

Hi. I've build a model consisting of 4 electrodes, soil and air. The two outer electrodes are assigned with current source. One with a positive magnitude and the other with a negative sign at the same magnitude. The four electrodes are dipped into a large rectangle (soil). The outer boundary of the soiI and air are grounded. The question is I need to calculate the resistance between the two inner electrodes but i do not know how to get the current current source. Please, someone help me!!
