SUMMARY
The discussion focuses on the instability of an infinitely long charged liquid jet, specifically addressing the effects of surface profile changes on surface charge density and electric energy. The energy change of the liquid jet is denoted as E, while the energy change in the connected charging system, operating at a constant voltage V, is -2E. The original paper referenced does not provide a proof for this result, prompting the inquiry into applicable theorems that could elucidate the phenomenon. A relevant resource is shared, which may offer insights into the stability of electrohydrodynamic (EHD) systems.
