JEE Mains · Physics · STD 12 - 14. Semicondutor electronics
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
Answer & Solution
Correct Answer
(C) A is true but R is false
Step-by-step Solution
Detailed explanation
In a reverse-biased diode, the current is very small and remains almost constant (known as reverse saturation current) until the breakdown voltage is reached. At the breakdown voltage (critical limit), the current increases drastically. Thus, Assertion A is true. The small…
