Question

In an n-p-n transistor `10^(10)` electrons enter the emitter in `10^(-6)`s. If 2% of the electrons are lost in the base, find the current transfer ratio and the current amplification factor.
A. `0.98,49`
B. `0.49,49`
C. `0.98,98`
D. `0.49,98`

Answer 1

Correct Answer - A
`alpha =(I_(c))/(I_(e)),I_(c)=(98)/(100)I_(e),beta =(alpha)/(1-alpha)`.
