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.

Choose the correct answer from the options given below.
- (A)Both and are true and is the correct explanation of .
- (B)Both and are true but is NOT the correct explanation of .
- (C) is true but is false✓ Correct
- (D) is false but is true
Answer: (C)
Solution
Under reverse bias a diode passes only a tiny, nearly voltage-independent reverse saturation current until the breakdown voltage, beyond which the current rises steeply, so the assertion is correct. This small reverse current is carried by the minority charge carriers, not the majority carriers, so the reason misstates the mechanism and is false. The assertion is true but the reason is false.
