Electric discharge in gases
Videos
Electric discharge in gases occurs when electric current flows through a gaseous medium due to ionization of the gas. Depending on several factors, the discharge may radiate visible light. The propert

Townsend discharge
Videos
In electromagnetism, the Townsend discharge or Townsend avalanche is an ionisation process for gases where free electrons are accelerated by an electric field, collide with gas molecules, and conseque
Electric discharge in gases
…In cold cathode tubes, the electric discharge in gas has three regions, with distinct current–voltage characteristics: I: Townsend discharge, below the breakdown voltage. At low voltages, the only current is that due to the generation of charge carriers in the gas by cosmic rays or other…
