Question

In a common emitter amplifier circuit using an n-p-n transistor, the phase difference between the input and the output voltages will be

(a) 90°

(b) 135°

(c) 180°

(d) 45°

Answer 1

Correct Option (c) 180°

Explanation:

In a CE n-p-n transistor amplifier output is 180° out of phase with input.
