Does plasma (physics) conduct electricity?

Plasma is ionised gas ie. Consists of free electrons and cations. Current is flow of electrons. Hence plasma can conduct electricity. Examples:- In DC metal arc welding process, plasma is created between the electrode and workpiece. read more

Hence plasma can conduct electricity. Examples: -In DC metal arc welding process, plasma is created between the electrode and workpiece. It is generally believed that electrons liberated from the electrode (cathode) strikes the workpiece (anode) generating large amount of heat. read more

Gases do conduct electricity, as all materials do. However, they conduct electricity so poorly that we consider them insulators. "Electricity" requires the movement of electrons. In a gas, these electrons are too dispersed to provided any measurable current. The "lightning" example is slightly different. This refers to capacitative discharge. read more
