Electrical resistivity and conductivity results in the important concept of "quasineutrality", which says the density of negative charges is approximately equal to the density of positive charges over large volumes of the plasma ("n" = <Z>"n"), but on the scale of the Debye length there can be charge imbalance. In the special case that "double layers" are formed, the charge separation can extend some tens of Debye lengths. The magnitude of the potentials and electric fields must be determined by means other than simply finding the net charge density. A common example is to assume that the electrons satisfy the Boltzmann relation: Differentiating this
Positive Songs for Negative People Positive Songs for Negative People Positive Songs for Negative People is the sixth studio album by English singer/songwriter Frank Turner. It was released on 7 August 2015 by Xtra Mile Recordings. The album garnered a positive reception but critics said it was derivative of Turner's previous works. "Positive Songs for Negative People" debuted at number 2 in the UK and number 69 on the "Billboard" 200 and spawned only one single: "The Next Storm". To promote the record, Turner toured across North America, Europe and Australia. On 15 June 2015, Turner announced a few UK tour dates on November to
