Question

the current gain of a transistor in common base configuration is 0.95 its current gain in common emitter configuration would be
A 0.95
B 95
C 19
d 1/19​

Answer 1

Answer:

(C). The current gain in common emitter configuration will be 19.

Explanation:

Given that,

The current gain of a transistor in common base configuration is 0.95.

The current gain in common emitter configuration will be

$\beta=\dfrac{\alpha}{1-\alpha}$

$\beta=\dfrac{0.95}{1-0.95}$

$\beta=19$

Hence, The current gain in common emitter configuration will be 19.
