The linear convective stability analysis of a poorly conducting liquid with inclined temperature gradient and under a vertical d. c. electric field is investigated. The liquid is placed between a parallel plate electrode system with the upper electrode heated. The eigenvalue problem is solved by the Chebyshev Tau-QZ method. Consideration is also given to the case when there is no horizontal flow and some interesting results are obtained. For inclined temperature gradient case, it is found that the onset of convection is governed by six parameters RV, RH, Re, Pr, Pe and Se. The effect of varying Re upon critical RV and RH is discussed and some considerations to the occurrence of transverse or longitudinal mode is pointed out.
