Corona discharge the electron-liberation is a high-energy photon from an atom within the plasma body relaxing after excitation from an earlier collision. The use of ionized neutral gas as a source of ionization is further diminished in a negative corona by the high-concentration of positive ions clustering around the curved electrode. Under other conditions, the collision of the positive species with the curved electrode can also cause electron liberation. The difference, then, between positive and negative coronas, in the matter of the generation of secondary electron avalanches, is that in a positive corona they are generated by the gas surrounding the plasma
Negative and positive rights both "positive" and "negative" duties, but it seems that rights that do not involve forced labor can be phrased positively or negatively at will. The distinction between positive and negative may not be very useful, or justified, as rights requiring the provision of labor can be rephrased from "right to education" or "right to health care" to "right to take surplus money to pay teachers" or "right to take surplus money to pay doctors". Negative and positive rights Negative and positive rights are rights that oblige either action ("positive rights") or inaction ("negative rights"). These obligations may be of either
