Question

In a transistor, if current amplification factor for common base configuration is 0.95, then current amplification factor for common emitter configuration will be

Easy

A

92
B

19
C

59
D

199

Solution

(2)
$\begin{array}{l} α = 0.95 \\ ∴ β = \frac{α}{1 - α} = \frac{0.95}{1 - 0.95} = 19 \end{array}$
