  • Question

  • The load impedance ZL of a CE amplifier has R and L in series. The phase difference between output and input will be


  • Options
  • A. 180°
  • B. 0
  • C. more than 90° but less than 180°
  • D. more than 180° but less than 270°

  • Correct Answer
  • more than 180° but less than 270° 

    Explanation
    It is 180° for purely resistive load and between 180° and 270° for R-L load.
