For a transistor `beta`=40 and `I_(B)=25muA` .Find the value of `I_(E)`

Text Solution

Verified by Experts

`beta=((deltaI_(C))/(deltaI_(B)))_(C_(CE))`(if only d.c values are considered)
`therefore I_(C)=betaI_(B)=40xx25xx10^(-6)=1000xx10^(-6)A`
`therefore I_(E)=I_(B)+I_(C)=(25xx10^(-6)+1000xx10^(-6))amp`
