Abstract
Current-voltage curves, using blade-plane electrodes in various liquids, whatever the polarity of the blade exhibit a sharp bend. At low fields, there is a linear relationship while at high fields, the current varies as Valpha (3< alpha <6), V being the applied voltage. Stationary field plots (using the Kerr technique) and transient current measurements show there is a homocharge injection by the blade. The injected charges, most likely ions, induce a liquid motion. This electrohydrodynamic (EHD) motion is thought to be the dominant factor in charge transport at high fields.Keywords
