The purpose of this experiment is

  • To investigate the characteristics of typical germanium and silicon semiconductor diodes, plotting voltage - current curves and find out the knee of the curve in each case.
  • To find that there is no-linearity below the knee and there is linearity above the knee.
  • To find that the forward bias voltage across the germanium diode is around 0.3 V and that of the silicon diode is about 0.6 V to 0.7 V
