Intuitive explanation[edit]

Is the required field...intense? Could we get an intuitive ballpark estimate of how intense? -- Beland (talk) 18:21, 6 February 2014 (UTC)

Very intense. I'm no physicist (just passing by), but have an amateur interest ... Air breaks down (so, when sparks form) at 30 kV/cm[1] or 3x106 V/m. So given that the Schwinger limit is at around 1018 V/m, that's a long way to go (about 1,000,000,000,000 times larger). Klbrain (talk) 22:50, 22 May 2017 (UTC)
