Question

For a common base configuration of $PNP$ transistor $\frac{{}^{l_C}}{l_E}=0.98$, then maximum current gain in common emitter configuration will be:

• A. $12$
• B. $24$
• C. $6$
• D. $5$

Answer 1

The correct option is B $24$

We know that in PNP transistor $\beta =\frac{\alpha }{1-\alpha }=\frac{0.98}{1-0.96}=24$.
