NEET Physics (general) MCQ Question
Type: MCQ-numerical-Hard-Class 12
A p-n junction diode is reverse biased with a voltage just below its breakdown voltage. If the breakdown voltage is 50V, what will happen to the diode if the reverse voltage is increased to 51V assuming no external current limiting?
A
The diode will conduct a large reverse current and be destroyed due to overheating.
B
The diode will continue to block current effectively without any issues.
C
The diode will break down and function as a short circuit permanently.
D
The diode will increase its reverse current slightly without damage.
Correct Answer
Option A
Detailed Explanation
When the reverse bias voltage exceeds the breakdown voltage, the reverse current increases sharply, potentially causing the diode to overheat and be destroyed.
