Junction Transistor

In a common emitter transistor amplifier, the output voltage and input voltage have a phase difference of

Show answer and solution

Answer: (d)

In CE mode, a rise in input raises $I_C$ , so drop across $R_L$ rises and $V_{CE} = V_{CC} - I_C R_L$ falls.
Output is inverted: phase difference $= 180^\circ = \pi$ rad.
So the answer is (d) $\pi^c$ .
