Question

Given below are two statements, one is labelled as Assertion (A) and the other is labelled as Reason (R):
Assertion (A): Emitter-follower configuration of BJT is used for impedance- matching applications.
Reason (R) : In a common-collector configuration of BJT, the output voltage at the emitter is in phase with input signal.
In the light of the above statements, choose the correct answer from the options given below.

• A. Both (A) and (R) are true and (R) is the correct explanation of (A)
• B. Both (A) and (R) are true but (R) is not the correct explanation of (A)
• C. (A) is true but (R) is false
• D. (A) is false but (R) is true

Answer 1

Answer: (B)

Both (A) and (R) are true but (R) is not the correct explanation of (A)

Answer 2
