• # question_answer 45) In the following common emitter configuration an NPN transistor with current gain $\beta =100$ is used. The output voltage of the amplifier will be- A) 10 mV              B) 0.1 VC) 1.0 V               D) 10 V

$\frac{{{V}_{0}}}{{{V}_{i}}}\,\,=\,\,\beta \frac{{{R}_{C}}}{{{R}_{B}}}$ ${{V}_{O}}\,\,=\,\,\beta \frac{{{R}_{C}}}{{{R}_{B}}}\,{{v}_{i}}$
