A) \[\text{1 }k\Omega \]
B) \[\text{3 }k\Omega \]
C) \[\text{30 }k\Omega \]
D) \[\text{30 }k\Omega \]
E) \[\text{6 }k\Omega \]
Correct Answer: B
Solution :
In common emitter amplifier Voltage gain = current gain x resistance gain or \[{{A}_{v}}=\beta \times \frac{{{R}_{o}}}{{{R}_{i}}}\] or \[\frac{{{V}_{o}}}{{{V}_{i}}}=\beta \frac{{{R}_{o}}}{{{R}_{i}}}\] or \[\frac{3}{0.01}=100\times \frac{{{R}_{o}}}{1\times {{10}^{3}}}\] or \[{{R}_{o}}=\frac{30}{0.01}=3\,k\Omega \]You need to login to perform this action.
