Streamer theory is used in describing the breakdown mechanism where the Townsend theory fails to explain some observations especially for gaps with larger pressure (pd) values applied to uniform field. With the aid of a diagram, explain briefly streamer's mechanism that caused the development of secondary avalanche (ionization)
