Question 86: Semiconductors and Logic Gates

Question

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 :

Accepted Answer

(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.
$$\Rightarrow$$ Statement R is correct explanation of statement A.

Answer

Both A and R are true, and R is correct explanation of A.

Answer

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

Answer

A is true but R is false.
