Related: About this forumdear du weather people .
i have been watching a lot of lighting storm videos lately. i know that there are several kinds of lighting including upward (positive ) and downward ( negative ) lighting. as in all electrical circuts , is there a return path. i was watching a video where a lighting scientist was talking about lightning to cccp students and they mentioned a return path. a puzzzle ment for me . thanks .

(2,182 posts)I am an electrical engineer and I install lightning protection systems per NFPA 780. A lot of terms get used like leader step, streamer, and return stroke. It all basically describes the process of development of an electric field and potential difference between clouds and cloud/ground, ionization of air, and discharge. I compare the complete circuit like the charging of a capacitor over time (evaporation, storm cloud formation). I see the leader step like a screwdriver placed across the capacitor (ionization/dielectric breakdown of air leader step) and the return stroke as the current discharge through the screw driver.
