PhysicsSingle correct+4 / -1Question 48 of 90

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 :

Both A and R true, and R is 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: A

Assertion and reason. In n-p-n transistors the main carriers are electrons, whose mobility is higher than that of holes, so they carry more current. Both true, and R explains A.

(A)
