MCQ
A transistor is used in common emitter mode as an amplifier. Then
  • A
    The base-emitter junction is forward biased
  • B
    The base-emitter junction is reverse biased
  • C
    The input signal is connected in series with the voltage applied to the base-emitter junction
  • ✓
    Both $ (a)$  or  $(c)$ 
✓

Answer

Correct option: D.
Both $ (a)$  or  $(c)$ 
d
(d)The circuit of a $ CE$  amplifier is as shown below

This has been shown a $ NPN$  transistor. Therefore base emitter are forward, biased and input signal is connected between base and emitter.
