Electronic Devices and Circuits - Engineering

Q1:

Assertion (A): Two transistors one n-p-n and the other p-n-p are identical in all respects (doping, construction, shape, size). The n-p-n transistor will have better frequency response. Reason (R): The electron mobility is higher than hole mobility.

A Both A and R are true and R is correct explanation of A

B Both A and R are true but R is not a correct explanation of A

C A is true but R is false

D A is false but R is true

ANS:A - Both A and R are true and R is correct explanation of A

Therefore mostly npn transistors are used.
