Townsend's criterion for a spark
WebThe Townsend criterion is of considerable physical interest but difficult to apply to engineering problems, whereas the semi-empirical streamer criterion, which holds for … Webthe electrical spark discharge. Although the electric spark has been known to mankind in its various manifestations from time immemorial, its mechanism has to date been little understood. The initial clarification of the mechanisms involved is due to J.S. Townsend as a result of his brilliant researches in the early nineteen hundreds. On the basis
