In a common emitter amplifier configuration, the current gain is 62 . The collector resistance and input resistance are \(5 \mathrm{~K} \Omega\) and \(500 \Omega\) respectively. If the input voltage is 0.01 V , the output voltage will be
- A 0.62 V
- B \(6 \cdot 2 \mathrm{~V}\)
- C 62 V
- D 620 V
Answer & Solution
Correct Answer
(B) \(6 \cdot 2 \mathrm{~V}\)
Step-by-step Solution
Detailed explanation
\(A_V = \beta \frac{R_C}{R_{in}}\) \(A_V = 62 \cdot \frac{5 \cdot 10^3 \Omega}{500 \Omega} = 620\)
