Electric potential in tap water and saline solution due to spark discharge on water surface

Abstract

This research aims to investigate the electrical characteristics when lightning phenomenon occurred on water surface. In this work, measurement of electric potential and electric field distribution in tap water when spark discharge occurred on water surface are discussed. This paper presents the electrical characteristics of breakdown and occurrence filamentary discharge, voltage and current waveforms, electric potential and electric field between tap water and saline solution due to spark discharge on water surface.
