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 Rare 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.
The Correct Option is A
Solution and Explanation
The correct answer is (A) : Both A and Rare true, and R is correct explanation of A.
(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
