Q1 FREE PREVIEW

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.

[04 April, 2026 (Shift-2)]

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.

✓ Correct answer: c)

A is true but R is false.

Explanation

Assertion A: In reverse bias, only a small leakage current flows (due to minority carriers), nearly independent of voltage, until breakdown occurs where current increases drastically. (Correct)
Reason R: In reverse bias, majority carriers do NOT flow - only minority carriers flow. R incorrectly states majority carriers flow. (Incorrect)
