Electronics Is soot/smoke electrically conductive?

Hi,
as above, just curious after seeing something on TV.

 

Well, carbon is a conductor...

I'd assume so, until proved otherwise.

A flame will be as there is ionised particles in it but pure soot should not be condctive. But how conductive do you mean? Im talking a few nAs

 

A flame actually acts as a rectifier diode, some gas burners use the effect to detect if they go out. http://www.fieldpiece.com/tech-articles-flame-rectifier.htm

Pure soot = carbon, a good conductor if a continuous film. One way of electroplating metal onto a plaster or rubber mould is to coat in soot first with a candle flame.

 

Many heavy smokers who smoke in front of their computers have noticed this when their computers suddenly stop working

 

You learn something everyday. dont know what I was thinking about soot.

 

There are some people here who know way too much for their own good haha. Man, every question and a professional answer.
