Assertion (A): It is not so easy to design d.c. amplifiers using transistors.
Reason (R): The values of hfe ,VBE and ICBO vary with temperature.
  • a)
    Both A and R are true and R is the correct explanation of A.
  • b)
    Both A and R are true but R is not the correct explanation of A
  • c)
    A is true but R is false
  • d)
    A is false but R is true
Correct answer is option 'A'. Can you explain this answer?

The values of hFE, VBE and ICB0 vary with temperature and due to the variation in any of these quantities the output voltage may change which may not be distinguished from a change in the input signal voltage, Due to this reason it is not so easy to design d.c. amplifiers using transistors. Hence, both assertion and reason are true and reason is the correct explanation of assertion.
