NEET 2026 Physics p-n Junction Diode Assertion Reason Question
Type: Assertion Reason-conceptual-Medium-Class 12
Two statements are given below:
A. When the forward bias voltage across a p-n junction diode increases above a certain threshold voltage, the diode current increases significantly.
B. This current is called reverse saturation current.
Choose the correct answer from the options given below:
A
Both Statements A and B are true
B
Statement A is true, but Statement B is false
C
Both Statements A and B are false
D
Statement A is false, but Statement B is true
Correct Answer
Option B
Detailed Explanation
In a forward-biased p-n junction diode, the current increases significantly beyond the threshold voltage. However, reverse saturation current refers to the small current that flows in the reverse bias condition, not in forward bias.
