JEE Main 28 June 2022, Shift 1, Physics Q48

Question 48 of 90 in this shift, Physics question 18 of 30, Section A.

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)Both $\mathbf{A}$ and $\mathbf{R}$ true, and $\mathbf{R}$ is correct explanation of $\mathbf{A}$ .Official answer
(2)Both $\mathbf{A}$ and $\mathbf{R}$ are true but $\mathbf{R}$ is NOT the correct explanation of $\mathbf{A}$ .
(3) $\mathbf{A}$ is true but $\mathbf{R}$ is false.
(4) $\mathbf{A}$ is false but $\mathbf{R}$ is true.
