The current gain `beta=100` and base current is `25 muA` . Calculate emitter current.

Text Solution

Verified by Experts

Given `beta=100 ` and `I_(B)=25 muA`
as `beta=(I_(C))/(I_(B))` (as `I_(E)=I_(C)+I_(B)`)
`rArr beta =(I_(E)-I_(B))/(I_(B))`
`rArr I_(E)=betaI_(B) + I_(B)`
`rArr I_(E)=100xx25 muA+25 muA`
`I_(E)=2525 muA =2.525 mA`
