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 base For example, the numbers from 100 to 109 have the same representations in decimal and negadecimal. Similarly, and is represented by 10001 in binary and 10001 in negabinary. Some numbers with their expansions in a number of positive and corresponding negative bases are: Note that the base expansions of negative integers have an even number of digits, while the base expansions of the non-negative integers have an odd number of digits. The base expansion of a number can be found by repeated division by , recording the non-negative remainders of formula_3, and concatenating those remainders, starting with the last. Note
