1. Question 1

   Q1. In a CE amplifier, the output voltage is

   • A) in phase with input voltage
   • B) out of phase with input voltage by 90°
   • C) out of phase with input voltage by 180°
   • D) out of phase with input voltage by 270°

   Answer: out of phase with input voltage by 180°

   Explanation: CE amplifier inverts the input signal, hence output is 180° out of phase.
