Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R
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.
Choose the correct answer from the options given below.
- A
Both A and R are true and R is the correct explanation of A.
- B
Both A and R are true but R is NOT the correct explanation of A.
- C
A is true but R is false
- D
A is false but R is true
Assertion: The reverse current is essentially the saturation current — small and nearly voltage-independent until breakdown, where it rises sharply. True.
Reason: In reverse bias the small reverse current is carried by minority carriers (electrons in p-side, holes in n-side), not majority carriers. The statement is therefore incorrect. False.
A is true but R is false.
