Question

In a PN-junction diode

• 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

Answer 1

Answer: (A)

The current in the reverse biased condition is generally very small

Answer 2

In forward biased PN-junction, external voltage decreases the potential barrier, so current is maximum. While in reversed biased PN-junction, external voltage increases the potential barrier, so the current is very small.
