Calculation of the critical conditions of instability in an electric field of a hemispherical droplet on a hard substrate

The critical conditions of instability of a hemispherical drop of a conducting liquid lying on a hard, electrically conducting substrate in an electric field parallel to the symmetry axis of the drop are found. These critical instability conditions are found to be higher than those of an insulating drop of the same size. Zh. Tekh. Fiz. 68, 9–12 (September 1998)
