Symbol for Current
[edit]This article uses i for current when usually the symbol is I (see https://en.wikipedia.org/wiki/Electric_current#Symbol). Is there a different convention for electrochemistry? 194.82.172.48 (talk) 09:15, 23 June 2017 (UTC)
Yes, it's usual to denote it as lower case i since in (Electro)chemistry. Why I don't know; two possible explanations: It ist often used together with length denoted as l and thus could be mistaken with I. Another explanation is that it is to avoid confusion with the ionic strength also denoted by I. 2001:67C:10EC:5746:8000:0:0:3D0 (talk) 12:49, 10 February 2020 (UTC)
