When a transistor is used as an Amplifier, the phase difference between the input and the output signal voltage is
- A \(\frac{3\pi}{2}\)
- B \(0\)
- C \(\pi\)
- D \(\frac{\pi}{2}\)
Answer & Solution
Correct Answer
(C) \(\pi\)
Step-by-step Solution
Detailed explanation
In a Common Emitter (CE) amplifier, which is the standard configuration for amplification, the output voltage is inverted relative to the input. As the input voltage increases, the output voltage decreases, resulting in a phase shift of \(180^{\circ}\) or \(\pi\) radians. C)…
