The phase difference between the input and output voltages in a common base arrangement is ___________

The correct answer is: A. 180°

In a common base arrangement, the input voltage is applied to the base of the transistor, and the output voltage is taken from the collector. The emitter is grounded. The phase difference between the input and output voltages is 180°. This means that the output voltage is inverted with respect to the input voltage.

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