Easy MCQ +4 / -1 PYQ · JEE Mains 2022

Given below are two statements : One is labelled as Assertion A and the other is labelled as Reason R.

Assertion A : n-p-n transistor permits more current than a p-n-p transistor.

Reason R : Electrons have greater mobility as a charge carrier.

Choose the correct answer from the options given below :

  1. A Both A and R are true, and R is correct explanation of A. Correct answer
  2. B Both A and R are true but R is NOT the correct explanation of A.
  3. C A is true but R is false.
  4. D A is false but R is true.

Solution

<p>(A) is true as n-p-n transistor permits more current than p-n-p transistor as electrons which are majority charge carriers in n-p-n have higher mobility than holes which are majority carriers in p-n-p transistor.</p> <p>$\Rightarrow$ Statement R is correct explanation of statement A.</p>
