Junction Transistor question from NEET 1990 (AIPMT)

Q130NEET 1990 · AIPMTEasy

Junction Transistor

In a common base amplifier the phase difference between the input signal voltage and the output voltage is

Show answer and solution

Answer: (a)

In CB mode, a rise in emitter current raises $I_C$ and the output voltage rises with it.
Input and output are in phase: phase difference $= 0$ .
So the answer is (a) $0$ .
