  • question_answer 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 V

    C) 1.0 V               

    D) 10 V

    Correct Answer: C

    Solution :

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