MCQ
In transistor, forward bias is always smaller than the reverse bias. The correct reason is
  • To avoid excessive heating of transistor
  • B
    To maintain a constant base current
  • C
    To produce large voltage gain
  • D
    None of these

Answer

Correct option: A.
To avoid excessive heating of transistor
a
(a) If forward bias is made large, the majority charge carriers would move from the emitter to the collector through the base with high velocity. This would give rise to excessive heat causing damage to transistor.
