Options:
  • A The current in the reverse biased condition is generally very small
  • B The current in the reverse biased condition is small but the forward biased current is independent of the bias voltage
  • C The reverse biased current is strongly dependent on the applied bias voltage
  • D The forward biased current is very small in comparison to reverse biased current

The correct answer is: The current in the reverse biased condition is generally very small
In forward biased $P N$-junction, external voltage decreases the potential barrier, so current is maximum. While in reversed biased PN-junction, extemal voltage increases the potential barrier, so the current is very small.
