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.

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.

Correct answer: A. Both A and R true, and R is correct explanation of A.

A n ‐ p ‐ n transistor has more electrons than holes, and p ‐ n ‐ p transistor has more holes than electrons. When a voltage is applied, then the movement of electrons is greater than holes. Therefore, conduction current in n ‐ p ‐ n transistor is more than that in p ‐ n ‐ p transistor. Both statements are true.
