(D) Given: Current gain in common emitter configuration,$\beta = 50$.Emitter current,$I_e = 6.6 \ mA$.We know that the relationship between current gain in common base $(\alpha)$ and common emitter $(\beta)$ configurations is given by:$\alpha = \frac{\beta}{1 + \beta}$Substituting the value of $\beta = 50$:$\alpha = \frac{50}{1 + 50} = \frac{50}{51}$$\alpha \approx 0.98$Thus,the current gain when it acts as a common base amplifier is $0.98$.

For a common emitter amplifier,the current gain is $50$. If the emitter current is $6.6 \ mA$,then the value of the current gain when it acts as a common base amplifier is:
