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.

Step-by-step solution

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.
