A) 4, 3.84
B) 3.69, 3.84
C) 4, 4
D) 4, 3.69
Correct Answer: A
Solution :
| [a] Given \[\alpha =0.96\] |
| So, \[\beta =\frac{\alpha }{1-\alpha }=\frac{0.96}{0.04}\Rightarrow \] |
| Voltage gain for common emitter configuration |
| \[{{A}_{v}}=\beta .\frac{{{R}_{L}}}{{{R}_{i}}}=24\times \frac{800}{192}=100\] |
| Power gain for common emitter configuration |
| \[{{P}_{v}}=\beta {{A}_{v}}=24\times 100=2400\] |
| Voltage gain for common base configuration |
| \[{{A}_{v}}=\alpha .\frac{{{R}_{L}}}{{{R}_{P}}}=0.96\times \frac{800}{192}=4\] |
| Power gain for common base configuration |
| \[{{P}_{v}}={{A}_{v}}\alpha =4\times 0.96=3.84\] |
| *In the question it is asked about common emitter configuration but we got above answer for common base configuration. |
