  • A
    Increases continuously with the forward current of the diode.
  • B
    Increases continuously with the forward current of the diode, reaches a maximum and then decreases.
  • C
    Decreases continuously with the forward current of the diode.
  • D
    Decreases continuously with the forward current of the diode, reaches a minimum and then increases.
✓

Answer

  1. Increases continuously with the forward current of the diode, reaches a maximum and then decreases.
