In a transistor (common emitter configuration) the ratio of power gain to voltage gain is (\(\alpha\) and \(\beta\) are current ratios)
- A \(\frac{\beta}{\alpha}\)
- B \(\alpha \beta\)
- C \(\alpha\)
- D \(\beta\)
Answer & Solution
Correct Answer
(D) \(\beta\)
Step-by-step Solution
Detailed explanation
\(\frac{\text{Power gain}}{\text{Voltage gain}} = \text{Current gain}\) For common emitter configuration, \(\text{Current gain} = \beta\)
