A theory of ball lightning as an electric discharge
... space charge density is 109 cm−3 . Such times are the order of magnitude of lifetimes of ball lightning and larger times would be predicted were we to use values of µ for ions rather than electron drift. In some applications, the above derivation for τ is expressed as τ = ε/σ , where σ = neq µe and ...

chapter 7 thermoelectric thermometry
... Peltier himself observed that, for a given electric current, the rate of absorption, or liberation, of heat at a thermoelectric junction depends on the Seebeck coefficient a of the two materials. Note that the Peltier thermal effects build up a potential difference that opposes the thermoelectric c ...
