    • @understandingelectricaleng2589
      @understandingelectricaleng2589 Год назад

      the difference between two configurations is the direction of electrons and holes that's all. Ofcourse the electron collector is anode and hole collector is cathode. Therefore, in nip We call it cathode and in pin We call it anode.
