    A transistor has current amplification factor (current gain) of 50. In a CE - amplifier circuit the collector resistance is\[1\,k\Omega \]. The output voltage if input voltage is 0.01 V

    A)  \[1.5\,V\]                                          

    B)  \[2\,V\]

    C)  \[2.5\,V\]                                          

    D)  \[3\,V\]

    Correct Answer: C

    Solution :

    \[\left( \frac{{{V}_{0}}}{{{V}_{1}}} \right)=\beta \,\left( \frac{{{R}_{C}}}{{{R}_{B}}} \right)\]           \[{{V}_{0}}\,=\beta \,\frac{{{R}_{C}}{{V}_{i}}}{{{R}_{B}}}\,\,=2.5V\]
