In a transistor, in common emitter configuration, the ratio of power gain to voltage gain is
In a transistor, in common emitter configuration, the ratio of power gain to voltage gain is
$\alpha$
$\frac{\beta}{\alpha}$
$\beta \alpha$
$\beta$
Solution
Power gain $=$ Voltage gain $\times$ Current gain
$\therefore \quad \frac{\text { Power Gain }}{\text { Voltage Gain }}=\text { Current gain }=\beta$
