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
Answer: (C) A is true but $\mathbf{R}$ is false
A is true: the reverse saturation current is tiny and almost constant until breakdown, where it rises sharply.
R is false: the small reverse current is carried by minority carriers, not majority carriers.
