InterviewSolution

1.	For a common emiter configuration if `a` and `beta` have their usualy meaning , the incorrrect relationship between `a and beta` is :A. `1/alpha=1/beta+1`B. `alpha=beta/(1-beta)`C. `alpha=beta/(1+beta)`D. `alpha=beta^(2)/(1+beta^(2))`
Answer» Correct Answer - B::D `alpha=I_(c)/I_(e)=I_(c)/(I_(c)+I_(B))=(I_(c)//I_(B))/((I_(c)//I_(B))+1)=beta/(beta+1)` or `1/alpha=(beta+1)/beta=1+1/beta`
