    • @physicskasafar
      @physicskasafar  3 года назад +4

      Photodiode basically light ko detect karne k liye use hota.
      Battery laga k hm reversed biased bnate hain.aur reversed biased mn current flow nai Karta.
      But jb light fall KARTi h to current flow karne lg Jata h minority charge carriers ki wajeh se
