JEE Main 2026 — 4 April, Evening Shift — Question 19
Assertion A: A diode under reverse-biased condition provides very small current which is nearly independent of voltage until a critical limit at which the current increases drastically. Reason R: Below the critical voltage limit, only majority charge carriers flow which increases drastically above critical voltage.
- Option A:
Both A and R are true and R is the correct explanation of A
- Option B:
Both A and R are true but R is NOT the correct explanation of A
- Option C:Correct
A is true but R is false
- Option D:
A is false but R is true
Answer: C
Step-by-step solution
Theoretical: In reverse bias, current is small and independent until breakdown (A true). Below breakdown, minority carriers flow, not majority. R is false because majority carriers do not flow in reverse bias.
