Junction Transistor question from NEET 2001 (AIPMT)

Q123NEET 2001 · AIPMTEasy

Junction Transistor

For a common base circuit if $\frac{I_C}{I_E}$ = 0.98 then current gain for common emitter circuit will be

Show answer and solution

Answer: (a)

$\alpha = 0.98$
$\beta = \frac{\alpha}{1-\alpha} = \frac{0.98}{0.02} = 49$
So the answer is (a) 49.
