Wat is Relation b/w Alpha n Beta...
 

Re: Wat is Relation

alpha=beta/(beta +1)
 

Wat is Relation

IE=Ic+IB
now divide both side byIB
IE/IB=Ic/IB+1
now since ic/ib=beta and ic/ie=alpha
we can get beta=alpha/1-alpha
and alpha=beta/1+beta
 

Re: Wat is Relation

beta known as a current gain of common emmiter amp..and relation with alpha is
α=β/(β +1)
