We need to disambiguate EMF, but I'm not into EE encough to know in this case whether it should point to electromagnetic field or Electromotive force. Someone please help. -Anthropos 13:06, 20 Dec 2003 (UTC)
It appears from the context that it should point to electromotive force, so I've changed it from the automated disambiguation.
Also, I've wikified Krishnavedala's contributions a bit. I've unlinked Image:Childlaw.JPG, which seems to me that it should be removed; I have no idea how to go about this. I think I've translated it to TeX properly, but the image was rather ambiguous. I can't say anything on the accuracy or relevance of what Krishnavedala has added; I'm only a sophomore physics major looking for stuff to clean up. If anyone can improve this section, please do so. 184.108.40.206 02:10, 9 Jun 2005 (UTC)
Krishnavedala image Childlaw.JPG
"I can't say anything on the accuracy or relevance of what Krishnavedala has added"
As far as I can tell, the Child's Law image ChildLangmuirLawGraph1.svg is just wrong. It appears to plot V^3, not V^(3/2) or V^1.5.
Unless somebody objects, I will post a graph of V^1.5.

I added definitions of the variables in the equation for Child's law.
- I cannot find any definition for ν. It is not in Child's original article (Phys. Rev. 32, 492 (1911)). Another paper I (randomly) found (Ang et al, Phys. Plasmas 13 056701 (2006) ) writes Child's Law as: . Numerically, one finds , as written in the current article. So I think the should be removed, and the numerical prefactor replaced by the relevant physical quantities. Chucklapuck (talk) 19:44, 15 October 2009 (UTC)
Mott's (?) steady-state space-charge-limited conduction
It is clear that the relation given in the section 'Mott's limited steady-state..' has anything to do with Mott? Can anyone give a reference for this? This expression already appeared in early papers by Shockley (see e.g. W. Shockley and R. C. Prim, Phys. Rev. 90, 753 - 758 (1953), Eq.(1.13)). Chucklapuck (talk) 19:44, 15 October 2009 (UTC)
It is also known as Mott-Gurney-Law (Space-charge Limited Current, SCLC). Hear the Cilds-Law is refered to as SCLC? But isn't SCLC ? Makes no sense... —Preceding unsigned comment added by 220.127.116.11 (talk) 16:14, 22 August 2010 (UTC)
what about non-high-vacuum?
"If the "vacuum" has a pressure of 10-6 mmHg or less, the main vehicle of conduction is electrons." this exposes only high vacuum conditions. what if I have a plasma within a gas at a pressure of, say, 15 to 40 torr? —Preceding unsigned comment added by 18.104.22.168 (talk) 06:20, 24 November 2010 (UTC)
