👉 The term "teff" is used in the context of nuclear fusion, specifically in the field of astrophysics. Teff (Temperature Effective Faraday) refers to the energy required for a given amount of matter to be converted into light as it is released when a reaction occurs between two atoms or molecules. This conversion can occur through various processes like nuclear fusion, which releases light and heat. In the context of nuclear fusion, the "temperature effective farad" (TEFF) refers to
