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