  Building on theories of Persson, we derive a simpler theory for
electroadhesion between rough surfaces using BAM (Bearing Area Model) of
Ciavarella, or previous ideas by Persson and Tosatti. Rather surprisingly, in
terms of stickiness, we obtain very simple and similar results for pure power
law power spectrum density (PSD), confirming stickiness to be mainly dependent
on macroscopic quantities. We define a new dimensionless parameter for
electroadhesive stickiness.
