Plasma (physics) potential in the space between charged particles, independent of how it can be measured, is called the "plasma potential", or the "space potential". If an electrode is inserted into a plasma, its potential will generally lie considerably below the plasma potential due to what is termed a Debye sheath. The good electrical conductivity of plasmas makes their electric fields very small. This 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 (formula_6), but on the scale of the Debye length
Negative and positive rights public debate between conservative ethicist Wesley J. Smith and bioethicist Jacob M. Appel. In discussing "Baxter v. Montana", Appel has written: Smith replies that this is "taking the duty to die and transforming it into a duty to kill", which he argues "reflects a profound misunderstanding of the government’s role". Presumably, if a person has positive rights it implies that other people have positive duties (to take certain actions); whereas negative rights imply that others have negative duties (to avoid certain other actions). Philosopher Henry Shue is skeptical; he believes that all rights (regardless of whether they seem more "negative"
