That is to say that in the plasma there is a mixture of positive nuclei and free electrons. That is why it is a state in which the electricity conduction.
Examples of plasma state
Sun. Like other stars, the sun is a plasma heated by nuclear fusion.
Solar winds. Movements in the atmosphere of the sun.
Nebulae. Made up of gases, mainly hydrogen and helium.
TV or monitor screens. Plasma displays contain neon and xenon gases.
Fluorescent tubes. Inside it is mercury vapor.
Electric arc welding. It can be done under gas protection.
Rockets. Rockets eject materials in a plasma state.
Fusion reactors. Inside, matter is in a plasma state.
Plasma lamps. Invented by Nikola Tesla to investigate high voltage.
Lightning bolts. During a thunderstorm, we can observe the plasma state in lightning that looks like lightning bolts.
Ionosphere. The part of the Earth's atmosphere that lies between the mesosphere and the exosphere.
