Question

For a transistor beta is 19 . Find the value of Alfa ?

Answer 1

Alpha), the factor by which emitter current is multiplied to yield collector current, can be calculated in two ways.


1st Way to Calculate Alpha α
If the β of the transistor is known, α can be calculated very easily by the formula:





Answer 2

alpha=beta/(1+beta)=19/(1+19)=19/20
