An n.p.n transistor with current gain β = 100 in common emitter configuration is shown in figure. The output voltage of the amplifier will be
Options
- A0 . 1   V
- B1 . 0   V
- C10   V
- D100   V
Correct answer
B. 1 . 0   V
Step-by-step solution
We know that, Voltage gain = Output   voltage Input   voltage Then, V out = V in × voltage gain. V out = V in × Current gain × resistance gain V out = V in   × β × R out   R in   V out   = 100 × 10 × 10 3 10 3 × 10 - 3 = 1   V
