We establish a correlation between the magnitude of a propagating crack in current-carrying flat samples and the change in the electric potential field over the surface of the sample when an electric current passes through it. The experimental data correspond to an analytic solution obtained using a conformal map in the two-dimensional formulation. This work can be related to the area of converting mechanical quantities into electrical quantities, which simplifies the process of recording mechanical processes and provides a convenient form for controlling and managing them. This work is aimed at the automatic control of the process of the destruction of conductive materials.
