Abstract :
The effect of residual conductivity on the stability of a horizontal dielectric liquid layer subjected to a weak unipolar injection and buoyancy is analyzed. Cases of heating from below and from above have been considered. Regions of steady and oscillatory instability are delineated by direct integration of the electrothermohydrodynamic equations for the case of constant mobility and permittivity
