Q127 / 180 · AIIMS 2015 · Physics

Assertion : In a common emitter transistor amplifier, the input current is much less than the output current than output impedance. Reason : The common emitter transistor amplifier has higher input impedance than output impedance

  • A
    If both assertion and reason are true and reason is the correct explanation of assertion.
  • B
    Ifboth assertion and reason are true but reason is not the correct explanation of assertion.
  • Correct answer
    C
    If assertion is true but reason is false.
  • D
    If both assertion and reason are false.

Solution

The output impedance is higher than the input impedance in a common emitter transistor amplifier.

Hence, the correct answer is option: 'C'.
