PhysicsSingle correct+4 / -1Question 45 of 75

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

Both A and R are true and R is the correct explanation of A

Both A and R are true but R is NOT the correct explanation of A

A is true but R is false

A is false but R is true

Answer and worked solution

Official answer: C

Assertion. Reverse current stays tiny and nearly constant until breakdown, then rises sharply: true.

Reason. Below breakdown the small reverse current is carried by minority carriers, not majority carriers: false.

(C)

Topics:Semiconductors and p-n junction
