The phase difference between the input and output voltages of a transistor connected in common collector arrangement is ___________

0°
90°
180°
270°

The correct answer is C. 180°.

In a common collector amplifier, the input signal is applied to the base of the transistor, the output signal is taken from the collector, and the emitter is grounded. The

phase difference between the input and output voltages is 180°. This is because the collector voltage is 180° out of phase with the base voltage.

Option A is incorrect because there is a 180° phase difference between the input and output voltages.

Option B is incorrect because the phase difference is not 90°.

Option D is incorrect because the phase difference is not 270°.
