First, Mathematical approach was used to derive an expression relating capillary ascent with the applied field. The results obtained from the experiment and that of the analytical results were compared with the expected results from the equation relating the liquid ascent and the applied field obtained from Lippmann equation, where it was observed that there is no evidence of linear relation between the height of the capillary rise of oil in the tube and the applied field. http://pubs.sciepub.com/ijp/2/3/3/ijp-2-3-3.pdf Electrocapillarity Dielectric parallel plates Electric field Palm oil Capillary rise
